It has been next to impossible to obtain fine quality Spinel specimens from Burma these days it seems. 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 rich purplish-red color. The crystal sits atop a matrix of massive white/grey Calcite as is typical for this locality. This piece was mined around 2000, and is one of the finest Spinels from the Rich Kosnar collection. Ex.
