This large cabinet specimen consists of a chunk of "Rainbow Specular Hematite". The Hematite has a lamellar, semicrystalline habit- it is not quite massive, but does not actually form crystals. It has the moderately high density, dark gray color and submetallic luster of the specie, and shows a colorful iridescence when viewed from certain angles under bright light. The colors are predominantly red and green, but some areas show small spots of blue color.
