Mineralpedia Details for Stolzite
Stolzite
Named for the man who provided the first specimen for study, Dr. Joseph Alexis Stolz from the Czech Republic. Relatively uncommon, Stolzite forms in the oxidized areas of hydrothermal tungsten-rich lead deposits. It can be found in many locations but only in very small amounts. Stolzite can fluoresce a bright red to orange under long-wave ultraviolet light and a bright lemony yellow under short-wave ultraviolet light. Often used as a scintillator due to its luminescence when irradiated.
