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.

This moissanite specimen is a typical cluster of silicon carbide crystals that precipitated on the walls of a blast furnace during the manufacture of steel. As such, it has a black color (due to a high level of iron impurities) and the crystals are opaque. They do have an excellent vitreous luster, and a colorful irridescent tarnish. The larger crystals are well formed thin hexagonal blades, while about half of the surface is covered by smaller distorted crystals that are often curved.

I like this moissanite specimen. It stands on its own quite nicely, has a cavity (and two exposed areas that were cavities until the adjacent mineral was removed), and the cavity is nearly round, and my first thought was that it was a drill hole, but then I noticed the excellent crystals growing into the cavity. These areas expose nearly perfect silicon carbide crystals that are larger than on the rest of the specimen, although in general the tiny crystals on the base yield to larger and larger ones towards the top. The colors are excellent here, too, with the violet, purple, and blue hues at the base yielding to greens, blues, and even nearly yellow irridescent hues near the top.

This moissanite specimen has especially brilliant irridescent colors in shades of blue, purple, green, and gold. It has an interesting shape at the top where the colors are most intense. Of course, like all such specimens, this one was formed in a blast furnace as an unintended by-product of the steel making process.

This colorful moissanite specimen can almost be described as a frozen rainbow - it displays a nearly continuous change of irridescent colors from gold through purple and blue to green.

The base of this chunk of moissanite (silicon carbide) is gray with bits of other materials from the blast furnace still attached. The sides are irridescent in shades of blue and green, while the top adds hues of purple. Some of the largest crystals (all are small) display irridescent hues from the entire rainbow.
