SOLD
Boracite is a rare borate found in evaporite deposits and this rare and fine matrix specimen is from the Type Locality - the Kalkberg Hill of Lower Saxony, Germany. Sharp, translucent, greenish, orthorhombic boracite crystals to 5 mm are nicely scattered in a cluster or as isolated crystals on the anhydrite matrix. The lustrous, brass-yellow pyrite cube cluster is a nice accent. Ex. George Elling Collection. Very rare in matrix richness, quality and association with pyrite. Older material.
