Man-made Spinel octahedrons (Whitmore Coll.)

Item Description

Striking, man made, super-well defined, stepped-growth, spinel octahedrons from a factory in Niagara Falls make for an impressive and unusual synthetic specimen. This piece has glass-like, sharp edges. The highly lustrous, deep purple crystals rest on a matrix of massive spinel. Seldom available on the market. Ex Robert Whitmore Collection.
