Bloedite is a rare hydrated sulfate found in oceanic and lacustrine salt deposits and in nitrate deposits in arid regions. This is an outstanding, large, cabinet-sized example of the rare species. This pristine, doubly terminated, dark gray, floater crystal is lustrous, transparent to translucent and has very sharp faces and edges. The chisel-like or boat prow terminations are fascinating and the doubly terminated accessory crystal is a fine accent. Excellent material from the Soda Lake area of California.
