Dioptase and Bayldonite
Thumbnail, 2.5 x 2.3 x 1.4 cm
Tsumeb Mine, Tsumeb, Otjikoto Region, Namibia

Superb thumbnail of GEMMY, highly lustrous Dioptase crystals framing a central valley of green Bayldonite crystals. The Dioptase crystals range up to 7 mm in size, and they sort of cascade down the valley sides going from larger to smaller, exactly like you would design it if you had the chance. As good as the pics might be, it is even better in person.
