A Tribute Dedicated in Memory to a Talented Facetor/Friend, Stephen Kotlowski (BS, GG(GIA), CSM)
Stephen Kotlowski in front of his ever present Ultra Tec, giving his "thumbs up"
frequently seen in photos. Note "some" of his awards displayed.
Jan. 5, 1953 - Oct. 20, 2015
Sad News for the Cutting/Gemstone Community:
Stephen Kotlowski, a Supreme Master Gem Cutter and Facetor of our finest colored gemstones,
passed away unexpectedly in Sedona, in October of 2015, where he had been living for the past five years.
His giving nature and willingness to share his decades of knowledge and experience with others who had
interest or the need, will certainly be missed. The owner of All That Glitters had met him for the first
time over 20 years ago (as both had been contacted by the first person to introduce Color Changing Turkish Diaspore to the trade),
and worked closely with him over the past 12 years for recutting and cutting the
finest color that was in the All That Glitters inventory. Though All That Glitters had used many fine cutters in the past,
including other award winners, Stephen was special in many ways and our very fine rough went to Stephen after 2003.
Stephen was extremely meticulous and patient when cutting difficult gemstones such as Diaspore and Kunzite. No one could re-cut a gemstone with such
a minimal loss as Stephen; he frequently created new cuts that were determined by the rough and didn't
work off of design diagrams. For these on-the-fly custom designs, he would use "UK"
(Uniquely K - for Uniquely Kotlowski) along with the general description of the shape to describe his new cut.
He won numerous awards in the AGTA Cutting Competition (as well as others) in the past.
The gemstone community has lost not only a master in cutting, but a gentle kind person who had many
interests he shared with others, was done to earth and freely gave his knowledge/help.
This page is dedicated to his work that we currently have in inventory or have recently sold.
AGS - Supreme Master (Faceting)
Portions of two emails from Stephen, 7/8/2012, regarding how he should be referred to in All That Glitters
News Releases and when mentioned in general:
"...this was the first and second years of the ASGC that was
created by Jerald Wycoff in Washington, DC and I entered the "The Competitive Evaluation" to see how I
would do under the Professional category and was lucky enough to win the first year and also the second year
which was required to do plus pass with a high score in a written Gemology general knowledge exam to be "Certified"
as a Supreme Master Gem Cutter under this new organizations rules...
this was the first ever evaluation that I had ever entered and I beat out some stiff competition of over 200 entries,
this all the while working for Kremetnz Gemstones as there Head lapidary... some really good times back then!..."
...attached is my current Bio plus photo documentation of my CSMG (its actually not just CSM, the proper way to display was CSM-F, F-
for faceting and then after completing the written test I was awarded CSMG the G replacing the F for Gemcutter the highest ranking)...

All gemstones below were faceted by Stephen Kotlowski (or re-faceted) from All That Glitters rough or gemstones that we both felt would
be enhanced and benefit by proper cutting/angles/polish. They are listed alphabetically by gemstone species. Photos of Stephen are scattered throughout.
55.88ct Synthetic
Alexandrite - Could be the largest ever faceted!
This large Synthetic
Alexandrite is from our Laser Rod material, and was
faceted by our Award Winning Supreme Master
Gemcutter - Stephen Kotlowski. We have many pictures showing the
progression from the rough to the finished gem seen
above. It measures 25.25x20.12x16.08mm.
The polish is incredible as our cutter used 200k
diamond powder in the final polishing step.
Depending on the lights, the body color is pinkish
red, amethyst purple and under a 65k Lumichrome Full
Spectrum light, the color can be a greenish, bluish
or teal. Normal lighting conditions show a
more purplish body color with teal or blue
highlights dancing around the internal
facets! We haven't been able to obtain
accurate color photos of Alexandrite or Ruby at
times, possibly due to the Chromium. The gem
may have a body color of teal to our eyes, but the
camera sees it as a very different color,.
Even when the office fluorescents show a
purple color, cameras are seeing bright pinkish
red! This was custom faceted for one of our
customers. It is up for sale using All That
Glitters as a broker, as our customer has home
repairs that require large sums of money. If
you have an interest in this this piece, please
email us for more details. SOLD!
This Large Blue Apatite from Madagascar weighs
in at 8.60cts and was faceted by our Award Winning Supreme Master Gemcutter, Stephen Kotlowski.
He has called this cut the Owl Half
Moon.
There is some green, making this a beautiful teal
color, but the predominant color is blue!
Unheard of in this size, cutting and clarity.
This rough was obtained in Madagascar over 10 years
ago!

Almost a 13ct ct Neon
Apatite!!
This Neon
Blue Apatite hails from the same country that
produced our previous neon Apatites, including the
ones that were photographed by GIA for a future
article. This particular gem was faceted
from a piece of rough that appeared in JCK
magazine. (The piece of rough is the largest
in the photo, and appears far more green in the
photo than in person.)
The All That Glitters Neon Apatites have received
much press because of their size, color and
clarity. This one falls into that category
too, but it was also faceted by our Master
Facetor, Stephen Kotlowski. Each facet meets perfectly. The
future owner could enter this piece into one of the
annual cutting competitions.
The color of this gemstone is diffrernt from the
other simiilar gemstones we have faceted. This
is not a true blue, but more of a bluish green
or deep teal. Unique Deep Bluish Green Apaptite faceted by our Master Cutter, Stephen Kotlowski, who called this color Caribbean.

A Cut Above the Rest - Stephen Scores Big (99.9/100) in Competition. His talent is recognized.
17.80ct Tajikistan Yellow Beryl
This beauty was just
returned by our Master Facetor (Stephen Kotlowski). It is a piece
of yellow beryl purchased about 10 years ago from
Tajikistan. The faceting is Competition
Cutting as is all work from this cutter. Every
facet junction meets perfectly and the life/sparkle
is incredible. This could be entered in a
cutting competition such as the AGTA Cutting Edge
Competition. 19.90x13.60x10mm

Edge Competition.

4.60ct Color Change Turkish Diaspore, Mixed 12 Main Brilliant Rectangle,
faceted by Master Cutter and AGTA Cutting Competion Award Winner - Stephen Kotlowski. This was
photographed under office fluorescent light and there was another light
source to the left. The main body color was a nice green and the flashes,
as you can see, were pink, reddish and even peach! Though great looking
under just fluorescent or incandescent light, we really enjoy seeing the
unique coloring and optical effects when two light sources are available.

4.68ct Color Change Turkish Diaspore, "Gone Askew Rhombus", faceted by
Master Cutter and AGTA Cutting Competion Award Winner, Stephen Kotlowski. This was
photographed under diffused office fluorescent lights, with a small
penlight illuminating the gemstone from above. The incandescent penlight
gives the peach, orange, red highlights. Depending on the light source, one
can see the following depending on those wavelengths available in those
light sources:
Office Fluorescent: Beige or beige-green
Brinkman Fluorescent: Better green than above
Diffused Daylight (by a window, under
a tree, etc.): Shows the best Green under the lighting conditions tested.

Stephen in his workshop in Newburgh, NY, where I used to spend many
hours with him viewing rough, trimming the rough and choosing pieces to leave with him to 'work his magaic".
Also learned how to facet here and even left my Ultra Tec with Stephen for some time as he tweaked
the machine to perform at it's best. He knew the Ultra Tec inside and out - literally...

6.05ct UK Start Cushion Round
This is a VERY lively gemstone. The color might be considered lighter in the
green or pink, but the sparkle is tremendous! Faceted by our Master Cutter (an
AGTA Cutting Competition Winner), Stephen Kotlowski. 12.21x12.21x7.90mm (trv-05-01i)
SOLD! (United Kingdom) Some of the customers comments are
below:
My stone arrived about an hour and a
half ago and ever since I have been walking around the house and outside in the
garden with it in my hand (carefully of course...). I must be honest and say that
I was prepared to be disappointed as you can never quite judge a photo and indeed
I have never seen this stone in the flesh before. I was wowed by the sparkle when
I opened the box - your website description is totally accurate in that this is
such a lively stone. I don't think I've seen a better cut stone and I certainly
don't possess one! The facet arrangements are unlike any I've seen before and I
was expecting a flat table for some reason from the photo but the cutting is
fantastic and I LOVE it. I imagine I will grow to love this stone more as already
I have seen a distinct colour change from my kitchen where it is a beige
champagne to outside where it is a bright almost lime green. I have seen some
salmon pinks running through but I'm sure these might come out more at night. It
is early days and I'm sure this stone will change and have different nuances
throughout the day and night which I haven't yet had enough time to look at and
appreciate. Thanks once again for the speed and efficiency of this transaction
and I will be back to purchase again in the future - as i said I do have my eye
on a spessartite garnet next but could be tempted also by another
diaspore.........

8.95ct Rare Color Changing Diaspore - Split
Facet Long Cushion Faceted by a well known Master Facetor - Stephen Kotlowski
Wonderfully cut with a nice color change. A few
inclusions under power, but not visible with the unaided eye. This is to be
expected within this rare gemstone. This was faceted by a cutter who has won
cutting competions, and in one case, it was for cutting Diaspore. The photos have
been color corrected to show what one sees under the appropriate lights. As a
rule of thumb, this material behaves in the following manner: Office Fluorescent
: Beige with Green over tones Indirect Daylight: Light to Medium Green
Incandescent light: Variation of light to medium Pink Mixture of two lights: Body
color is green with wonderful peach high lights internally Call or email for
price quotes.
Stephen in his workshop, new location(?) - Sedona, AZ.
9.00ct Color Change Turkish Diaspore, "Compass Rose" Apex Cushion, faceted
by Master Cutter and AGTA Cutting Competion Award Winner, Stephen Kotlowski. This was
photographed under diffused office fluorescent light with a fiber optic
light source to the left. The main body color was a nice green and the
flashes, as you can see, were pink, reddish and even peach! Office
Fluorescent: Yellowish Green Brinkman Fluorescent: Deep Celery Green
Diffused Daylight (by a window, under a tree, etc.): Wonderful green,
similar to some Tourmaline Incandescent/spot: Bronzy Pink or Peach Note
that the name of this cut comes from the fact that it does not have a flat
table, but has numerous facts that create a cross or compass design. This
gem has some inclusions which is typical of Diaspore. The cutting hides
them nicely. Like natural Alexandrite, one must typically understand the
material and know that color, size, cutting, inclusions and color change
are usually a tradeoff. Contact us to learn more or for a price. (11.40 x
10.80 x 9.95mm)
Another INCREDIBLY
Brilliant, Sparkly, Eye Clean Diaspore faceted from our rough by our Master
Cutter (an AGTA Cutting Competition Winner) - Stephen Kotlowski. The faceting design is a Modified
Princess Rectangle - but for all intensive purposes, it is a square, cut with
similar facets to a Princess Cut, thereby giving it Lots of Life! This beauty
weights a whopping 9.05cts. In this case, we decided to use the cameras setting
to simulate different lighting conditions. It is very difficult to get accurate
color photos of most gemstones that color change. Typically, the camera sees a
different color than what the eye sees. The colors seen in this gem, obviously
vary depending on what lights are available. We have seen a beige, smoky green,
yellowish green and a champagne pink - and all variations in between! Dimensions
of this piece are: 11.70x11.09x8.87mm (aldrov-06-01c)
10.90ct UK 5 Star Portuguese
Round! We haven't seen a round in this material before; perhaps the most
difficult shape to obtain because of the habit (shape) of the original Diaspore
crystal. Faceted by our Master Cutter (an AGTA Cutting Competition
Winner), Stephen Kotlowski. 14.20x9.12mm (trv-05-01g)
11.15ct UK Formee Cross
Rectangle Very lively as you can see. Lots of life and a very decent green. Would
describe the pink as possibly a smoky pink or dark pink champagne. Faceted by our
Master Cutter (an AGTA Cutting Competition Winner) - Stephen Kotlowski. 13.12x11.00x10.47mm
(trv-05-01h)
11.25ct Flash Keystone A very
interesting shape and play of life within the stone. The interaction of the light
acts as if there are two different stones - the left side and the right side.
Colors can be different on either side at the same time - have seen green on one,
and pink on the other! Faceted by our Master Cutter (an AGTA Cutting Competition
Winner), Stephen Kotlowski. 18.47x(9.86x6.56)x8.44mm (aldrov-06-01d)

capture the true color green and that is why we photographed this in incandescent
light showing the good pink! Faceted by our Master Cutter (an AGTA Cutting

26.25ct Rare Color Changing Diaspore - Modified
Opposed Bar Rectangle Faceted by a well known Master Facetor, Stephen Kotlowski
An incredibly large and clean example of the
rare gemstone. Under very bright lights, one inclusion can be seen. This is to be
expected within this rare gemstone. This was faceted by a cutter who has won
cutting competions, and in one case, it was for cutting Diaspore. The photos have
been color corrected to show what one sees under the appropriate lights. As a
rule of thumb, this material behaves in the following manner: Office Fluorescent
: Beige with Green over tones Indirect Daylight: Medium to Deep Green
Incandescent light: Medium to Deep Pink, Red highlights Mixture of two lights:
Body color is Green with wonderful Peach, Orange, Red hilights internally
28.51ct UK Brilliant Square;
The largest Diaspore that we currents have in inventory, with the largest one
being a 33+ct gem since the introducation of this material to the trade back in
about 1995. At 33+cts, we had a News Release that a World Class Gemstone had
found a new home - a collector/investor on the West Coast! Faceted by our Master

Last faceted gem from the bicolor crystal of Kunzite, originating in the

Cutting Edge Competition, but the cut off date for entries was like last week!
Another unique custom cut that one could call a Trilliant-like Pear, or a
Trilliant or a Pear-like Trilliant. It would look stunning set as a pendant;
possibly a pearl enhancer?? This was photographed under diffused natural light
and depending on the lights, it will have that wonderful blue secondary color as
has been seen from the unique crystal that it was faceted from. Color has been
described as purple, but lights will make it look more pink or purple, and both
colors may show that blue glow. This measures in at a whopping 47.82cts with
dimensions of 21.40 x 23.30 x 18.03mm. (ovml-12-03d)

41.80ct
Bluish Purple California Kunzite, Oceanview Mine, Big Kahuna Zone approx late
2010 (1st gemstone from an unique bi-color crystal!)
Our Award Winning Master Cutter, Stephen Kotlowski, has completed an incredible
Kunzite from a mine in the United States. This is indeed the color, a moderately
deep bluish purple and was photographed under 65K Natural Daylight/Full Spectrum
Lumichrome light. In diffused natural light inside as well as by a window, the
wavelengths do allow this gem to show more purple, with hints of blue. The pinker
image on the right is more typical of what one sees under office fluorescent and
incandescent light. This 41.80ct Modified Trilliant measuring 20.00 x 20.00 x
20.00 x 17.80mm (ovml-12-03a) (This is at the wholesale price for a
Kunzite that doesn't have this expert faceting, or the color and clarity. When
all is said and done, this is below wholesale for such a fine example of Kunzite
- and it is American Gemstone too, as well as Natural!)

faceting.... Faceting Kunzite Demo
Those in the jewelry trade saw this gemstone for the first time
in early December. Mr. Brown, owner of All That Glitters was traveling and took
one gemstone to show two people he had met previously - a GIA Gemologist and a
Custom Goldsmith. When asked what they thought this gemstone was, the first guess
was Amethyst; that was followed by a second guess of Sapphire. These two similar
guesses were made by two individuals that were about 100 miles apart and with
different backgrounds. Perhaps the very high polish (200k diamond) made them
think this was Sapphire, but the color certainly points to Amethyst
initially.
In the above table was a link that showed the step by step faceting of the most saturated gemstone
from the large Oceanview Mine Kunzite Crystal. Stephen took pains to document the angles and the indexes of the gems
he faceted - and it was necessary since he wasn't working off of faceting diagrams but creating custom
designs on the fly. If he had to go back to any facets due to issues, his notebook with the indexes/angles would be
required. He usually documented the cutting process with photos, and noted issues encountered, again with photos.
He also frequently took more time to insure that the facets/facet junctions could clearly be seen in the photos.
In the case of this Trilliant Kunzite, we both agreed that we would document the cutting. We talked on the phone (and emailed)
to insure that the text was appropriate for the photo displayed and chose the best photos to document the process. Changes would be made to photos, text and more,
then uploaded on line so that he could view and critique the changes; the process continued until the displayed content was correct. This was all done prior to going live with the page.
This is great documentation for the cutting of a gemstone by Stephen,
and I copied the link and placed it here in hopes that those visiting his page do indeed view it.

California Kunzite from the
Oceanview Mine, the Big Kahuna II Pocket!
Recent gemstone rough finds in San Diego Co. included the new Spodumenes from
the Oceanview Mine. During the 2010 mining of the Oceanview Mine, the 'Big
Kahuna' Zone was discovered. This was a large pocket with a series of smaller
satellite pockets. The zone yield Spodumenes, Quartz, Tourmalines and Beryl.
However, on 19 December, they encountered another rich zone: the Big Kahuna II. This zone, on the Baker Boulevard
level, may be a down-dip continuation of the Big Kahuna zone that was dug on
the next level above (Carter Court level) earlier in 2010.
The above rough was faceted by our Master Cutter, so this means every facet meets perfectly and
this piece could be entered into the AGTA Cutting Edge Competion. Due to the
cutting, polish, color, sparkle and rarity of the material, and the fact that
is an American Gemstone, it could possible win in one of the categories!

The above price is the wholesale price seen in Tucson 2012 at the GJX Show, International
Section, by Brasilians selling a fairly deep pink Kunzite faceted (as well as
in the rough). Their material was irradiated - our California Kunzite is
natural. Also, at just under 19cts, ours is much smaller than the 60ct to
100cts or so pieces of the irradiated material that is required to show a
decent color.

Sapphire faceted by our Master Facetor, Stephen Kotlowski. Fairly typical for Aussie Sapphire, but
it is a well faceted, over 2 carat Blue Sapphire and priced to move. (ogm-07-01b3)
The Oregon Sunstone Rough shown above produced the faceted gemstones
you see below. One can get a good idea of some of the waste of the original
rough, as one can see the trim marks where a diamond saw blade will remove
cracks, inclusions and areas that are not desired in the finished faceted
gemstone. The typical yield that we use when estimating a finished gemstone
is 20% - meaning that 80% of the rough that is paid for, is literally
trimmed and ground away. Note that the rough piece on the left produced the
gemstone in the photo you see below. You can see some of the
glittering schiller in the piece of rough. The green outline (watermelon)
was removed so as not to mix the green with the reddish orange, as there
was a high likelihood that this would muddy the color and the final
gemstone would not be the nice pure color you see below!
A Very Large Natural 9.93ct
Oregon Sunstone, mined in 2009 and faceted in the U.S. by our Supreme Master
Gem Cutter - Stephen Kotlowski. This is a dusty orange under office fluorescent lights, but a
bright orange under lights such as incandesents. There is a decent amount
of schiller without being overpowered by schiller. It causes a slight
sleepiness which is very common in these gems with schiller. It is still
bright, it certainly glitters internally and externally (our Master Cutter
is responsible for the high polish!) and is a wonderful example of a large
orangy Natural Oregon Sunstone! 12.45x11.35x10.60mm (dd-09b-02)
Note - Production this year, 2009, has been quite low due to mechanized
mining failures. Problems continue to plague the
complicated mechanisms which must all act as one unit. We were only one of
two that were allowed to view this rough and make a selection. The owner of
All That Glitters personally chose these two pieces of rough from this very
limited selection.
Faceted Tanzanite
Rough Terminated Crystal that Produced Faceted Gem
Above is a 5.25ct Master Faceted Tanzanite faceted from the
wonderfully naturally terminated crystal also shown above. Like all of our
inventory, we hold nothing back - though many very fine gemstones are
purchased or faceted, ALL are offered for sale. In this case, we offered a
very special terminated Tanzanite crystal as a collector piece. We never
displayed it in a show or offered it to dealers - we only displayed it on
our website. There were no takers, so reluctantly, we had our Master Cutter
(Stephen Kotlowski) facet this wonderful gemstone from the rare crystal shown above.

Original Bicolor Piece of Rough
Another Rarity in the Gem World - A
Natural Green Tanzanite, faceted by our Master Facetor, Stephen Kotlowski.
This 4.60ct Scissors cut is a dark
pastel green to a deeper green depending on the lighting available. The
ends appear to pull in blue or purple from the other axes of the gem, and
when tilted, the colors blend, going to teal... Note that if one turns
the stone on the side, one of the other other pleochroic colors, in this
case a purplish blue, is very evident. With the price of the standard
colored Tanzanite increasing and being controlled by one company, similar
to DeBeers and diamonds, all of this material is priced higher and the
more unique colors are even harder to encounter than previously - and in
the past, a unique color was far and few between. This gemstone measures
approx 12.26x6.30x6.13mm (neg-07-01)
Here are the cutters
comments regarding this gemstone after he faceted it! "...the color shift and the
flash of the cutting is really fantastic...the photo's are good but can't
show the scintillations that this chameleon of a stone
possess..."
The piece of rough is
shown above. It was originally a bi-color, being green AND blue, but 50% of
the rough could not be used. The blue section was essentially thrown away
and a waste. Here is another case of ones hopes being dashed, but the final
result of a green or teal Tanzanite makes up for it!

NEON Blue Tanzanite - Faceted by our Master U.S. Cutter - Stephen Kotlowski!
Trimmed Original Piece of Tanzanite Rough The
only other piece we know of is in Russia - Wish we had bought
it!
What is the more costly - Purplish
Tanzanite or Blue Tanzanite? The consensus over the years has been that
the blue is less common, more desirable and more expensive. Many
Tanzanites will color shift and a blue body color will become purple
under incandescent lighting. So, what happens when a unique Neon Blue
Tanzanite is found? RARE, RARE, RARE....! The trade doesn't see this
material and it usually never finds its way to the public - generally
purchased immediately when first seen by the trade and those in the
business. When one hasn't seen anything like this in 26 years of dealing
with gems, one's mouth drops. Even if not in the business, one would
question what gemstone this is. It is a unique blue. This gem glows.
There is no purple under any lighting conditions. The color can best be
described as the Best Blue Zircon color. This was faceted by our Master
U.S. Cutter, Stephen Kotlowski, who has won cutting competitions for his work. This gemstone
is no different - every facet meets perfectly. It is also clean! The
piece of rough that faceted this gem is shown above. The price below
reflects what one might expect to pay for a Tanzanite of normal color, of
this size. This is from old inventory of many years ago; stashed away by
a couple in the business who knew this was special. They sold the
standard colored Tanzanite to the trade and public, keepingt this behind
for their own personal collection!....Dimensions of the finished gemstone
9.15 X 7.90 X 5.85(d)mm (gf-07-01)
(This is about what one would
expect to pay in a store for a similar sized medium saturated Tanzanite
of the standard expected color. As someone in the trade said of this color
- try finding another one - regardless of what one has to spend!)

A 6.35ct Nuristani
Tourmaline of a Teal Color - our Master Cutter, Stephen Kotlowski, called it "Fine Teal Blue"
and the design is what he calls "Switch Diamond Rectangle". A few
inclusions as can be expected from this color and location. Color varies
depending on the light available - halogen, fluorescent, incandescent,
direct sunlight, indirect sunlight/shade, etc. Measures approximately
14.56x7.55x6.36mm (norgem-98b10c)
8.95ct Nuristan Green-Blue
Tourmaline faceted by our Award Winning Master Facetor - Stephen Kotlowski! Other photos
showed more brilliance, but we liked the play of light in this photo.
Though all facets have flat sides, the optical effects show more of a
wavy appearance in this photo! 20.00x7.57x6.92mm (nrstngm-96aj1)
Two Nuristani Tourmalines faceted by our Master Facetor (Stephen Kotlowski), total weight
of 11.23cts. The larger of the two weighs 6.57cts and is more of a
beautiful pure green, whereas the smaller one, weighing 4.66cts has hints
of blue. 4.66cts 12.68x7.32x5.55mm (nrstngm-97b1b) 6.57cts
12.74x8.66x6.48mm (nrstngm-97b1a)
6.80ct Bicolor
Tourmaline from Nuristan faceted by our U.S. Master Cutter, Stephen Kotlowski. When one looks
straight above onto the gem, one sees blue on one side and green on the
other. Tipping it slightly turns his gem either all blue or all green! Both
blue and green are very fine colors with no detracting modifiers. Some fine
inclusions as is to be expected with this fine color, but nothing that is
very noticeable or detrimental. 17.27x7.50x5.26mm (nrstngm-96b1a)
Tourmaline from the Congo - Africa!
9.31ct Tourmaline - Faceted by Master Cutter and AGTA Cutting
Competition Award Winner - Stephen Kotlowski!
This tourmaline is from the new find of tourmaline making
its way into the wholesale market currently. After faceting, it will
eventually trickle down to the retail stores and then the public. Like all
other gems, this material has it's fine quality as well as lower quality.
This is a wonderful example of the color, which can be a very pleasing
green with blue. Like many of these fancies colors, there can be some
inclusions. This has a few but the cutting hides them under most
conditions. The cut is a newly designed called a Switch Back Emerald Cut.
It will twinkle and the flashes of light will bounce rapidly from the top
of the stone to the bottom of the stone as it is tilted. A very unique cut!
This is a large, well cut, teal to green Congo Tourmaline measuring
14.55x9.50x7.22mm. (hilbos-04a-01) Note - this is the nicest piece of Congo
Tourmaline we have seen and a very fine color for Tourmaline. As seen in

A - 13.00ct Fine Blue with a hint of Green. From the famous
Golconda Mine in Brasil. The mine has been closed for many decades and
the rough was purchased by All That Glitters over a decade ago and
finally faceted by a Master Cutter and AGTA Cutting Competition Award
Winner, Stephen Kotlowski. 12.10x12.10x9.98mm (atoz-97b-01a) SOLD! (United Kingdom)
B - 17.30cts Very Fine Mint Bluish Green Tourmaline Faceted by the
Master Cutter and AGTA Cutting Competition Award Winner (Stephen Kotlowski), cut into a
"Double" Switchback Emerald Rectangle measuring: 16.44 x 11.41 x 10.06m
The rough was a doubly terminated tourmaline crystal and was purchased
a decade ago. It originated in the high mountains in the Nuristan area
on the borders of Pakistan and Afghanistan. This is an inhospitable
place for both humans and the pack animals that are required to bring
the necessary tools and supplies to this rugged area. (nrstngm-96a1h)

well known West Coast business. Priced back in 2007. Call or email if you
have an interest. Only one like this!Gemstones - New Edition
Stephen sold and was a representative for Ultra Tec, a faceting company/machine
that he had decades of experience with. If you knew Stephen, he frequently faceted MANY hours a day and into the early morning
hours. My last conversation with him on October 9, 2015 (Friday), he indicated that he had just finished
recutting a very costly large Diaspore (with VERY little loss!) - that was at 6AM and it was early afternoon. He had yet
to get any sleep. The phrase "Why Not Cut a Gem Today, seems very appropriate when considering Stephen's devotion to cutting.
He was very enthusiatic about gemstones, minerals and cutting, and it would please him tremendously to be responsible
for someone becoming interested in cutting. He was responsible for my obtaining an Ultra Tec, teaching me the basics, modifying
my machine to work at it's optimum as well as making small additions and tweaking that he had learned (the hard way) during his
decades of working with this brand of machine.

4.00ct Round Mozambique Tourmaline, Royal Purple. This
color is rare as well as the shape. Have not seen ANY rounds of size in
this gemstone. Also, this was re-faceted by our Master Facetor, Stephen Kotlowski, who recently
won an award in the ATGA Cutting Competition. (kaek-06-02) Preliminary tests using a spectrometer do indeed show
this to be Cuprian Tourmaline. Measures approximately 10.4x6.6mm
Photos do not do this gemstone justice - color is richer in person!

9.60ct Green Mozambique Tourmaline. This was recut by

Don't mind my Dust!.... Hard to get photos that don't show

4.46ct Mozambique Tourmaline, Oval, bright neon green
depending on the lights (yahya-06a-02) This is similar in color to the
trilliant you see below. Three similar gemstones were purchased at the same
time. The color was very bright and said "Buy Me" , so we had to purchase
all three. They consisted of a trilliant and two ovals. The other oval is
also pictured below and was recut by our Award Winning Master Cutter, Stephen Kotlowski. It
too is certed, but the cert no longer shows the current carat weight after
recutting. (The cert will accompany the recut gemstone and is similar to
the certs you see for the oval above and the trilliant below - Natural
Tourmaline)
5.09ct Neon Green Mozambique Tourmaline. This was recut
by our Master Cutter, Stephen Kotlowski, to create a better looking gemstone. There is a
certificate with this gemstone that indicates it is a natural Tourmaline.
The cert is now outdated because the dimensions and the weight has changed.
Some inclusions as can be expected in this color as well as the origin of
this gemstone. Eye visible, but really doesn't affect the sparkle of the
gemstone. This photo doesn't do this gem justice. (yahya-06a-01) SOLD!
8.62ct French Baquette
Orange Tanzanian Zircon, U.S. Faceted by our Supreme Master Gem Cutter - Stephen Kotlowski! (hilbos-05-02b)
14.38ct Red Zircon
"Mixed" Brilliant Diamond Cut 14.94 x 11.47 x 10.14(d)mm faceted by
Master Cutter and AGTA Cutting Competition Winner, Stephen Kotlowski. (hv-05-02) This
is a very unique piece as it has a color shift. It is very dark under
fluorescent lights and looks like a smoky orange. However, under
incandescent light, it is a bright red, very similar to ruby or chrome
pyrope garnet. This could contain chromium, which explains the color, but
the fact that there is a color change along with the intense red, make this
a very unique and unusual piece. We haven't seen or heard of anything like
this previously, nor has our cutter. We could not obtain a decent
photograph of this gem and had to rely on the photograph that the cutter
had taken. Oh, and another plus for this gem, it is very large for a nice
zircon! This photo shows the gemstone fully illuminated with lights.
In closing, we will end with the photo that we began with.
It is now time for your friends, colleagues and admirers to give you a much deserved Thumbs Up...
Thumbs Up to Stephen Kotlowski (BS, GG(GIA), CSM), Supreme Master Gem Cutter!...
You made many friends both in this country and internationally. Your incredible talent, friendship and experience/knowledge that you freely
shared will be greatly missed by many.
