Item Description
Chromite is a multiple oxide with Cr and is a member of the Spinel Group. It is found as a cumulate mineral layer in ultramafic igneous rocks, in peridotites or with associated placer deposits. It is also common in meteorites except carbonaceous chondrites (MINDAT). The sharp black metallic octahedron has a resinous luster. Pristine. A contact on one corner has no damage, per se. That's brown wax on one face. Probably older material from this obscure locale, but no proof. Ex Carl Davis Collection. Rarely on the market in this quality.
