There’s a Fungus Among Us, But It’s Definitely Not This Gem

Identify me to win a free t-shirt in INSTORE’s monthly contest.




I don’t blame René Just Haüy; he just wanted a Greek-inspired name that reflected the way I “scatter” when put to the blowpipe flame. Still, my name evokes images of toenail fungus in the minds of many. So it’s no surprise I’ve become better known by trade names such as csarite, ottomanite, turkizite, and zultanite, which play on my connections to the Anatolian Mountains, the only place I’m found in gem quality.

Who am I?

Guess this gem for a chance to win a “Jewelry Geek” T-shirt. Be sure to include your full name and the name and address of your store. The contest winner will be selected from among correct answers to this question.

Wilkerson Testimonials

To Generate Funds for a Jeweler’s Move and Remodel, Wilkerson More Than Delivered

Even successful jewelers need a little extra cash to fund expansion plans—especially when there’s inventory on hand that’s ripe for liquidation. For Beaumont, Texas-based jeweler Michael Price, co-owner of Mathews Jewelers, it was the perfect time to call Wilkerson. Price talked to other jewelers as well as vendors for advice during the selection process and decided to go with Wilkerson. And he wasn’t disappointed. When it comes to paying for the move and expansion, Price says the road ahead is clear. “When we close on the next two stores, there’s no worries about finances.”

I Am Rare, Stunning and Contain a Gemological Mystery in My Core

I am California’s official gemstone (no Googling allowed!).




I AM ONE OF the world’s rarest gemstones and one of gemology’s greatest mysteries — science has been unable to explain my color, nor has anyone been able to artificially reproduce my crystal structure. First found in California’s southern Mount Diablo range in 1906, I am today that state’s official gemstone. Shreve & Co., the famed San Francisco store, led the drive to market me as a jewelry stone but despite my stunning brilliance — my dispersion is only slightly less than that of a diamond — I have never caught on with consumers (I am a little soft and usually very small in gem quality samples). Nevertheless, I remain highly prized among collectors.

This Former Luxury Gem Bathes in the Orange Glow of History

It’s said the prophet Mohammed wore a silver ring set with it.




TODAY THE TERM “luxury goods” means Louis Vuitton handbags, Chanel No. 5 perfume and high-end jewelry, but there was a time when it meant frankincense and myrrh and me. This was especially the case in and around the old Muslim world, because of the way I could be carved and used as a seal. There is even a story that the prophet Mohammed wore a silver ring set with a seal carved from yours truly. Agate, aventurine, chrysophrase … I share numerous characteristics with my chalcedony brothers, but none bathes in the same deep orange glow of history as I do.
