This is a large colorful moissanite specimen, crystallized on the wall of a blast furnace during the production of steel. Moissanite (silicon carbide), is exceedingly hard (only diamond beats it), but the specimen is still rather brittle. Instead of being transparent, it is colored black due to the heavy concentration of iron impurities. The surface of the moissanite displays bright irridescent hues of blues, purples, and golds. The crystals are all flat with prismatic shapes, and while I do not see any hexagonal crystals, the angles indicate hexagonal form. Many of the crystals have interesting growth patterns on their surfaces. Many small pieces will fall off duing handling (and shipping, for that matter), but this will not detract from the specimen's appeal.
