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 | |

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!) |

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.
