Synthetic Alexandrite Rough

Our Last Synthethic Alexandrite Rough was Sold on 3/27/17.

Thanks to everyone who has purchased this material over the past 10 years.

GREAT NEWS! After waiting for 10 years for a new pull, we have one coming in and the rough will be available for sale by the end of May if all goes well. It is a large pull with a few laser rods/cores removed. We have to visit a facility that can slice the pull and then each slice must be trimmed to remove the 'holes', producing various sized pieces that can be sold. If you wish to be added to a list of those seeking this rough when available, members of the list will be contacted prior to any postings elsewhere, and these individuals will have one week before we officially go public indicating that the rough is available for sale.

This is wonderful material to even test out a new cutting design. We like it better than using clear quartz or very inexpensive material, as when the gem/design is complete, it has a good value so one can recoup his time in cutting - unlike having a nice flashy piece of clear quartz...

US Created Synthetic Alexandrite for
Laser Rod Applications - Czochralski Pull Method

Above photo is from the 2008 Pull - the rough is for sale below. When looking through the slice to the sky or through a window, the color is a green, blue green, yellow green or slight orange, depending on the orientation - it is hard to hold it perfectly perpendicular, so other colors from the pleochroism can show through. Looking through the edge, it is a deep ruby red. The reddish areas you see in the slice are most like rough saw blade marks. I believe that this interferes with light and is picking up other axis color, therefore showing these reddish/purple smudges. In a polished slice (both side), one only sees a pure color. Note the core - the very center is clean, and the outside edges of the clean area have inclusions and the remainder of the slice is clean. When we trim, we trim out the core and the surrounding inclusions as one piece and offer it at a greatly reduced price. Included areas have made nice cabs in the past.

Note that in full slices of the pull shown below, the very center has a area that is totally clean, perhaps the size of a dime and this will cut a round gemstone. Around this clear area, there is an area that contains some inclusions and these areas are great for cabochons - which would be unique as most of this material is typically faceted. The remainder of the slice is clean. John Koivula has looked at these inclusions and had the following to say - "Thanks for letting me know that the Czochralski rod was grown in the US. Since Czochralski pulling from a melt is generally the same no matter where it is done it is not too surprising that similar inclusions could be founds in rods produced by different growers." John now has a sample of our material in his collection. You can learn more about John's interest in inclusions, whether natural or lab grown, in his multi-volumed "Photoatlas of Inclusions in Gemstones".

Also note that a wholesaler and cutter in the Mid-West has purchased a few slices of this material, and with his cutting, he sells the finished gemstones for between $50/ct-$150/ct depending on whether the client is a dealer or retail customer, and the design, etc.

Below is a photo of a piece of rough similar to that are typically available.

Example of a 12mm round that we faceted. We are not sure if we oriented it properly, but regardless of this, the color is really nice, the material is clean, etc. This was from a previous pull that was received.

11.15ct Square Dozen Cut from this rough.
We have the results from two stones being cut from two different orientations. There is also a third orientation to try and again, all kinds of other possibilities if you go off-axis! One orientation yielded the following color change under the lights that we checked: Incandescent light - purplish pink; office fluorescent - purple with tanzanite blue highlights; under a Brinkman Fluorescent light (which we use when purchasing color change rough or color changing stones - teal blue with some purple highlights.
Another stone was cut at a different orientation. It goes from a purplish pink under incandescent, to a green with purple highlights (Brinkman) and under office fluorescent, it is really unusual - one can see green, purple and yellow orange occurring on the diagonals. This could be due to the orientaiton and/or the cut, but the play of color is wonderful. The camera was picking up what the eye was seeing, so no photos exist. It is the same cut (square dozen) and weighed 6.51cts.
Quote from the U.S. Cutter who faceted the two stones from the Pull discussed above: "I felt that the color was very good on both stones.....
I did like the color, even the color change was good. As you had said earlier, the matl. is not as dark as the Russian matl. and will show better in larger stones."

"I just finished my first stone from the Alexandrite lab rough I purchased from you. Thought you might like to see. 10.19ct, Paver Trilliant design by Jeremy Newman, cut by me... One photo in natural light, other under fluorescent. Nice material!! I have bought some years ago and cut it, not nearly as nice as this."

This material is a by-product of laser rod manufacturing. The application of this material as laser rods involves the Medical, Cosmetic, Spectroscopy and Industrial fields.

We purchased a large Pull as seen in the photos above and the pieces of rough below have come from that very piece.. We have sold this material to manufacturers outside the U.S. and it was always by the kilo. The Chinese were also faceting it and selling the cut gems.

We were asked by a number of small businesses and cutters to sell smaller pieces, so this time, we decided that we would break up a pull.

The color under incandescent light is reddish pink; under fluorescent lights, it depends on how one orients the axes. Using a dichroscope, one can see purple, teal, blue, green, orange and yellow. We have cut a few pieces here in the US from a previous pull and it goes from reddish pink to purple with teal - see photo above. At 15+mm in diameter, the color is strong without orientation of the rough. Note that this material is lighter than other Alexandrite out there and it allows one to cut very large stones without the being too dark. It contains less Cr and therefore, has less saturation. The largest faceted gemstone that has been faceted is over 70cts - and it still is not overly saturated! Parcels typically consist of a range of different sized pieces - see the photos above.

Write us for any more info, etc. This is nice material for cutting for your personal use or for resale.

NOTE - This material is generating a lot of inquiries. If these parcels are gone, we will put you on a waiting list for future parcels. Just contact us via email below and let us know that you require! (Wait time in the past has been about 3-6 years or so before we obtained new material in the past)

As some of you already know, other companies offer this material up to twice this price and with that material, one cannot facet larger stones because of the color saturation - NOT this material though........

Most of the material on the market is the darker material which does not allow larger stones to be faceted. Anything larger than 6mm is too dark! Some of these companies are also delivering rough which is only 5-8mm thick - ours is fairly thick , though we have cut a few pieces at 10mm. We will continue to slice at about 12-17mm thick.

What does ON HOLD mean??? People have expressed an interest in purchasing the material and we are currently awaiting payment, verifying payment has been received or awaiting final approval. SOLD indicates the material has been received and accepted.

Interesting Facts:
1.) The Pull seemed to be either a pinkish red or purple prior to cutting. It was difficult to obtain different colors with the dichroscope. As soon as a slice was cut, the dichroic colors that Alexandrite is known to have, appeared - the same exact colors seen in the previous pulls...
2.) Why wasn't this Pull used for Laser Rods. The Chromium content of this material is the same as previously purchased, so that was not an issue. The length of the Pull was too short to be used for laser rod manufacturing - so the Pull was never cored...
3.) One of our cutters used his 630-680nm diode laser and pointed to a faceted gemstone and the rough. The material went from a purplish pink color to blue green and remained like that for a few minutes. Other lasers would most likely have some affect on the color, as one is 'pumping' the atoms of the material. He also saw fringes. This material would most likely be used to create a tuneable laser...
4.) When the Pull has been sliced, holding the slice up to our office fluorescent lights, an orangy color is seen. If held up to outside light and looking through it, one sees a green color. Using the dichroscope looking through the slice, one sees an orange and a teal. Rotating the slice 90 degrees and looking through the edge, the color is Ruby Red!
5.) Down what we believe is the the C/Optic Axis: Teal/Orange
Side: Purple/Orange
90 deg to above: Teal/Purple
Tipping it just right will also give a yellowish green and purple; have seen pure green too. Simply Amazing Material!
6.) We have much fog from the valley outside the windows of our West Coast office. Holding a slice of the rough in front of a window at dusk with the white of the fog acting as a background, a wonderful green color is observed.
7.) A flat screen monitor acts as a dichroscope because of the polarized light. Rotating a slice produces a beautiful teal color and continuing to rotate, the rough turns orange.
