Gem Quiz: I Was Once ‘For Collectors Only,’ But Now More People See My Value

mm

Published

on

INSTORE clinozoisite 2I was once one of those minerals most aptly described as “of interest to collectors only,” but recent scientific research has found uses for me as a “fixing agent” in the production of hydrogen gas for use in fuel cells and secondly as an element in protective clothing. While I was discovered rather late (1896 in Tyrol, Austria), I’m a fairly common calcium aluminum silicate and take my name from my resemblance to a companion in the Epidote series. All pretty heavy stuff, I know. But when not hard at work with serious science nerds, I can be faceted to form a very pleasing cut stone.

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.

I recommend them highly.”

Olivine? Peridot? Beryl? No … I Am The Deceiver

Consider this a test of your knowledge of the Mohs scale.

I SHOULDN’T HAVE TO say more than I’m the defining mineral for 5 on the Mohs Scale of Hardness, and the hands of 20,000 knowing jewelers should reach for the sky … but then I’d have to stop talking about myself and I am a fascinating character — one with a real hunger to be all things to all people. I’m used to clean up nuclear waste, to fluoridate water, and to manufacture fertilizer. I am in your teeth and bones and while I am only infrequently used as a gemstone, I have been mistaken for much more valuable minerals such as olivine, peridot and beryl. Hence the Greek origins of my name — I am the deceiver.

This Gemstone Sounds Like An Evil Planet or Skin Disease, But It’s Really Quite Delightful

This green stone offers emerald-like beauty at a fraction of the price.

Published

ZIRCON, VARISCITE, AMMOLITE — some gemstones sound more like evil planets or skin diseases than something that could be turned into jewelry. I, too, suffer from a less than romantic name, although it’s probably a car polish that first comes to mind when you hear me mentioned. Still, what my over-literal namers lacked in inspiration I make up for with my emerald-like beauty. At a relatively low cost and readily available since Siberia’s mineral riches began flowing into the market, I make a great choice for earrings. I tend to be a little soft for ring duty — and no one is going to ask why you’re selling industrial agents as center stones.
