A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Hematite is an iron oxide mineral (Fe₂O₃) that typically appears metallic steel-gray to black in gem form, with a characteristic reddish-brown streak. It has Mohs hardness about 5.5–6.5 and no cleavage, but it is relatively brittle and heavy, with high specific gravity (~5.2). It is opaque and valued for its metallic luster and weighty feel rather than transparency.
