Transparent blue Gahnite crystal, the zinc rich end member and one of the rarer species in the Spinel group of minerals. A complete octahedron with one tiny chip on one tip, otherwise perfect and one of the sharper most perfect crystals I've had of this material. It's also transparent and appears all facet grade internally. These were first discovered in 2001 and are found mostly of industrial quality. Though they don't get very large, the color is spectacular. The GIA has written a nice article about these crystals published in Gems & Gemology, Fall 2019, Vol. 55, No. 3.
