Does Hematite a Make Good Jewelry Stone? Gem cutters often make cameos, intaglios, carvings, beads, and cabochons from hematites. Occasionally, gem enthusiasts may want these opaque, sub-metallic gems faceted, with flat bases and few facets (like a classic marcasite).. Although reasonably tough with a hardness between 5 and 6.5, hematites are also brittle.
