Quartz with Calcite and Sphalerite (ex Rich Kosnar Collection)

Item Description

A wonderfully aesthetic and eye-catching display specimen of sharp, somewhat lustrous, prismatic "milky" Quartz crystals with associated very pale pink, narrow scalenohedral crystals of Mn-bearing Calcite plus some brownish colored Sphalerite at the base. A few superficial nicks on some of the Quartz crystals do not take away from the overall aesthetic appeal of the piece. The specimen was mined in the 1970s and comes from the noted South American collection of Richard A. Kosnar.
