My Mineral Collection, Sphalerites Page

This is my sphalerite collection. I have enough of them that they deserve their own page. Sphalerite forms beautiful and often complex crystals. Their color can range from (rare) colorless through shades of green, yellow, orange, red, brown, and black - all determined by the amount of iron impurities. (Pure synthetic zinc sulfide is colorless.) Faceted sphalerite is gorgeous - it has twice the dispersion (fire) of diamond! Sphalerite is also trimorphic with wurtzite and matraite.

Sphalerite

This is a very handsome specimen of red sphalerites on (and in) radiating quartz from Shuikoushan (probably the Kangjiawan Pb-Zn-Ag-Au deposit), Hengyang, in the Hunan Province of China. Some of the sphalerites are 3 cm on an edge! There's also black zones in some of them. Also, there's a couple of pockets of tiny white calcite rhombs. Interspersed among the quartz are numerous "nailhead calcites".

Thanks to Chris Korpi at Pangaea Minerals for the specimen!
