Matrix specimens of Spinel are uncommon, but to find gem quality crystals on matrix is extremely difficult. This piece hosts a classic Burmese "Ruby Spinel" crystal with very sharp, defined, lustrous, octahedral faces and a gemmy, bright pinkish-red color. The crystal measures 7 mm across and sits atop a matrix of massive white Calcite as is typical for this locality. The piece is very fine and aesthetic for the material, and certainly not easily replaced in this market. This piece was mined around 2000, and is one of the better matrix Spinels from the Richard Kosnar collection.
