Here’s the Answer to January’s Gem Quiz




And congratulations to our winner.

Gary Hurdle, sales manager at Casa de Oro in Corpus Christi, TX, is the winner of January’s Gem Quiz. Gary crushed it (excuse the pun — trapiche ruby was the answer) and will soon take proud ownership of a Jewelry Geek t-shirt. Well done, Gary, as well as all this month’s Honorable Mentions for providing the correct answer. Next month’s Gem Quiz will be appearing online soon. Please look out for it.

This Gem Is Like Quartz, but a Lot Wetter




If it weren’t for my high water content (anywhere between 3-20 percent), they say I’d basically be quartz. Which to me is like saying that if Lake Superior didn’t have water it’d be a prairie. Huh! A lake is a lake and quartz I am not. What I am is a soft, delicate, HYDRATED silicate of a certain healthy hue that is sometimes referred to as quinzite (and which yes OK, under some conditions can look like quartz).
Who am I?

Gem Quiz

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.
