Since it is August, the month that claims Spinel as one of its birthstone options, it seems fitting to share a little more about a Spinel mine Rachel, Bjorn, and I visited in early July in the Morogoro region of Tanzania. This is really as primitive as it gets, using only hand tools and their own sweat. No explosives. No power tools. Spinel is a gem that actually occurs in a huge range of colors, though the red to pink colors are mostly found in this region. They hadn’t found any transparent, gem quality spinel yet at this mine, which only increases my understanding of a gem’s true rarity.

Who has spinel for a birthstone, owns a spinel, or is spinel’s #1 fan? Leave a 🤩😃😍 in the comments!

Because Peridot only occurs in one color, I think many folks think it’s overrated. (Don’t tell anyone but I would probably agree.) UNTIL THIS ONE. This is the most underrated of all the overrated Peridots I’ve ever seen. Comment with your opinion!

Most gems are “allochromatic” meaning that they can occur in every color because their chemical makeup allows for different trace elements to color it. Peridot is one of a few gems that are “idiochromatic,” meaning that it doesn’t have any flexibility in its recipe and it can only occur in one color!

The Tourmaline crystal naturally grows long and thin, so finding a crystal big enough to make a 15 and a half millimeter round is like winning the lottery for a gem cutter! 🤩 This 18.76ct Pink Tourmaline from Nigeria is kind of pink and kind of peach, depending on the lighting, but it is bright and lively all the time! Available on rogerdery.com and a portion of the proceeds is donated to @thegemlegacy.

Ginger and I are road-tripping south to visit my sister and her husband and to the Franklin Faceting Symposium where I’m teaching a seminar for other gem faceters on gemstone dopping (attaching the gem to a dop - the stick that holds the gem during the faceting process). Join us in my stories!

After 20+ years of being a gem faceter and 35+ years married and working with gems together, it took my wife Ginger going back to Tanzania with me to get her hands dirty and learn to pre-form / pre-shape at the Gemological and Gem Faceting School we support through @thegemlegacy. 😆 I just stood back and experienced her enjoyment of the process! There’s never been a day I’ve wished for another career, but it certainly increased my appreciation for the work I have the honor of calling my “job”.

What questions do you have for Ginger after her first try? 😃
