Based on a specimen from Yekaterinburg, Russia

This model is based on a very unusual but completely natural specimen, and there is a story behind it as well.

Most of the time, I model specimens that are in my personal collection. I’m not strict about this rule, but having a guideline in place prevents me from being distracted by all the gorgeous crystal drawings out there, and keeps me from spending all my time modeling beautiful rarities that I’m not likely to see in person. But just this once, I allowed myself to be persuaded by the incredible form of John White’s “Odd Garnet” described in the March/April 2025 issue of Rocks and Minerals magazine.

I bought the crystal fragment this model is based on at the Tucson show in 2022. It’s about the size of my thumbnail, and around half complete. While it’s a pretty shade of green, it’s not gemmy, and certainly not undamaged. According to objective standards, it’s not a great specimen, and not the type of crystal most collectors are looking for, but I dug through about 6 flats of “better” specimens to find it. What attracted me to this specimen was its complex and interesting crystal habit. But, as you can see in the photo, it’s difficult to see all the faces clearly and tell how they are arranged, so I made an idealized CAD model to better represent what the crystal would have looked like if it had developed symmetrically.

Surprisingly, some of the most unique crystals I have modeled have been garnets. The odd garnet described here and the complex tsavorite shown here are examples. This is another. The garnet crystal that this model is based on is elongated along one of its fourfold axes, making it look tetragonal instead of isometric. It really doesn’t look much like a garnet at all, and it took a little while for me to convince myself that that’s what it was!
