Sulfoborite: Mg3B2(SO4)(OH)8(OH,F)2
Comments: Colorless transparent sulfoborite crystal. Location: Lake Inder, Atyrau, Kazakhstan. Scale: See Photo. © Jeff Weissman / Photographic Guide to Mineral Species
Sulfur: S8

Sulfur: S8 Coccinite: Hg++I2 (?)
Comments: Orange-red coccinite on sulfur. Due to the volatility of the mineral at room temperature, the sample is preserved in a closed vial. The photo was made through the vial, therefore the sharpness is reduced. Location: Lichtenberg Mine, Ronneburg U Deposit, Gera district, Thuringia, Germany.
