To compare All That Glitters Pricing on available Tanzanite with expected retail pricing on Tanzanite, scroll down to the last Tanzanite in this table. Retail for about an 8ct Tanzanite, of lesser color than our large almost 8ct pear shape, is at $2000/ct whereas the typical purple/blue All That Glitters Tanzanite price per carat is not even half of that and our similarly sized pieces are better in color!

7.69ct Incredibly Vivid glowing Blue with some Purple, Pear Shaped Tanzanite. Perfect for a ring or pendant when it it worn. Photos don't do this justice. This is the best of a small parcel that we picked up relatively recently - prices are expected to increase on these fine Tanzies, if they haven't already. Would make a great pendant but a ring is very possible too! Tanzanite has such an appealing attractive color and could be worn by a man or a woman; the owner of All That Glitters wears a ring with a Tanzanite that was cut by All That Glitters cutters back in the 1990s. This particular Tanzanite puts most others on the market to shame - and it is a relatively small gemstones without having to be very large (and therefore much more costly). This photo is perhaps the most accurate in color that we were able to obtain, but many gemstones, such as this one, are difficult to photograph and obtain the accurate color that the eye sees. This gem, as well as the Elongated Cushion above, are the deepest richest glowing color in this small parcel. (ik-23-05) Contact Us for Pricing.

In keeping with All That Glitters' Unique and Rare Gems, here is another colored version of Zoisite - a Green Zoisite; some call this Green Tanzanite or simply Fancy Tanzanite, as it is the same mineral as Tanzanite, but can be found in various colors. This interesting freeform weighs 4.27cts and one can almost expect that a larger piece of rough may be faceted in such a way to utilize this rare material. Faceted in the U.S. by a Multi-Award Winning Cutter who is represented in museums. (ggc-20a-03) Contact Us for Pricing. (The original cutter was seeking about $8,000 for this unique beauty!)

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. 14.70x7.59x5.19mm (eagt-03-04) $6,563
2 pieces of Tanzaznite weighing 1.73cts(1.05ct and 0.68ct). The camera has caught more colors than the eye sees because it is such a closeup of these stones. The color is more of a steely blue with purple highlights coming from the side. These were faceted from a section of rough that produced a large green Tanzanite - the rough was actually bi-colored, being half green and half blue. Unfortunately, there was not much facetable material on the blue side. Due to this fact, it is a loss at the price we are currently offering these two gemstones at. (neg-07-01a) $346

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) $10,810
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!

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) $8,500 (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!)

2.94ct Trilliant, U.S. Faceted - A beauty! (neg-03093) $3,675
*** Note - this gem was featured in an article published in the May Issue of Jewelers Circular Keystone (JCK) Magazine. The color of this gem was originally green. Heat changed it to the color that most expect Tanzanite to be! Most Tanzanite is found in the earth as a brown colo. It is heated to produce the blue/purple color. Naturally occurring Tanzanite can be brown, blue/purple, green, yellow and pink. To see the article and photos, click on the link below:

This large Tanzanite has rarely seen the light of day since it's purchase back in about 1990. It has a certificate from Guild Laboratories in Los Angeles, CA, along with a photograph and with a retail price of $27,000 - that was back in 1991! Charles Carmona, owner of Guild Labs, is a well known respected Appraiser/Gemologist - who has appeared on The Peoples Court and has worked in various developing countries - I believe invited by The World Bank. As noted by Charles during the appraisal process, there is a small needle deep in the stone only seen under power - this indicates that it most likely would not have been heated, as most Tanzanites come out of the ground as brown color and have to be heated to obtaine the blue/purple that those expect. Some rough we have seen is indeed blue when mined (as well as a few exceptional pieces that might be fancy colors) - so most likely this large gemstone did not require heating as the coefficient of expansion of the needle most likely would have caused the needle to expand and crack the rough/gemstone. Having this needle pressent is a plus.

The very fine larger pieces are becoming quite scarce and prices have been going up - but Tanzanites are one of those gemstones that is known to fluctuate depending on what is being found, though supply is limited; though this mineral can be found in a few other countries, the fine color such as this one or even just a good blue/purple, purple blue, is just not found elsewhere.

No photos can do this item ANY justice! The color glows with life similar to a Kashmir Sapphire. Other lights will show the color as having purple highlights. We have included a number of various photos under various lights, showing it more blue, more purple and even purple blue. The video was shot with lights where you can see more people. This would make a killer pendant or perhaps even a pearl enhancer - if being customer designed, one could design a piece that could be a pendant, a pearl ehancer as well as a pin! Some people might even consider it for a ring - it is a large gemstone but for the right person, this could be worn as a ring!

Appraised back in 1990 at $27,500, perhaps we could have sold it then, but we put it into the vault since we were not ready to sell this beauty yet. The prices back then and the uncertainly of the deposit, made it one of those gemstones to place aside for the time being. The future of the Tanzanite deposit is still uncertain, but it is still being worked, material is sporadic, but one thing is for certain, the deposit is LIMITED and in time will be worked out and Tanzanite as we know it will be a rare commoditiy - no longer being actively mined, but will have to be purchased on a different level/market.

We have inclusded a screen grab of another large Tanzanite seen in the past few years for sale as a comparison.

This 24.97ct Tanzanite is sold with the original cert, as well as the case it has been store in all these years. Video was shot under lights with more purple available in the wavelengths. (rma-91-02#) Contact Us for Pricing.

This gem was a hard one to photograph! The camera and lights were making the gemstone look much darker when photographed head on. This color above is simlar to the true color, but in person, the color could be somewhat darker. I would describe it as a light purple, periwinkle or lavender. It really depends on the lighting conditions, the angle, etc. Clean, well cut - has the color one expects of a smaller Tanzanite. Deeper color will be achieved by a larger stone. (gembkk-06-02) $299

Note: Magnification and bright lighting is required to photograph gemstones.  Some inclusions may be visible under these circumstances. You are viewing photographs as if you were using a loupe or microscope - not your unaided eye.  Under normal conditions, these inclusions may not be visible.
