Certified 24.97ct Glowing Blue Tanzanite from the early 1990s!
About the Item
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 included 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 noted above, as well as the case it has been store in all these years - see photos.

- 4.27ct Freeform GREEN Zoisite (same mineral as Tanzanite!) Unique Cut & Color!Located in Methuen, MAIn keeping with All That Glitters' Unique and Rare Gems, here is a gemstone that most people are familiar with but don't know that it can come in various other colors (purple, teal, green, yellow, gold, pink and colors in between). The mineral is Zoisite and when it is a Blue Purple or Purple Blue, it is called Tanzanite. This ia a Green Zoisite; some call this Green Tanzanite or simply Fancy Tanzanite. Most Tanzanite comes out of the ground as a brown color and is heated to obtain the blue/purple; however, some is apparently heated natural in the ground and we have purchased the rough in various colors. Because this body color is Green, this would not have been heated. Zoisite/Tanzanite is trichroic and as the rough or gemstone is turned to look at all three axes, different colors can be obversed. You can see purple in some directions as this piece is viewed from the side. This interesting freeform weighs 4.27cts. This beauty was Faceted in the U.S. by a Multi-Award Winning Cutter who is represented in museums. (Initial owner/cutter was seeking about $8,000 for this unique beauty from the trade, but we have a good rapport with this cutter and we can offer this to the public at about his original price.) Photos have not been color corrected. Color and Brilliance is much better in person. For those seeking the standard color of Tanzanite, we do have a fine selection of high grade Tanzanites...Category
