Sphalerite (var schalenblende) from the Pomorzany Mine, Olkusz, Poland. A favorite desk specimen, given to me by a mine geologist there.
Exhibits typical concentric brown to yellow fine grained mineral layers, along with galena, pyrite. #MinCup26 #MineralMonday ⚒️ -

Mineral Monday: Memorial: Dr. George Rossman
By Dr. George Harlow
His research focused on color in minerals, the effect of high-energy radiation on color, and the role of “water” (H2O, that is) in minerals, esp. when not part of the chemical formula.
