Store separately from diamonds, rubies, and sapphires as they can scratch the gemstone.

Imitations: Usually made mostly of compressed iron and was marketed as “hemetine”, but that trade name was ruled misleading by the FTC.
Most pieces sold today as "Hematite" beads or carvings, especially those that are highly magnetic, are actually a man-made, ceramic-ferrite material called "Hematine" or "Magnetic Hematite" (often a mixture of iron oxide and strontium ferrite). Natural Hematite is only weakly magnetic or not magnetic at all.
Synthetics: Natural Hematite is not synthesized for the jewelry market. "Rainbow Hematite" is often a natural Hematite coated with a thin film of an iridescent material, or it may be a heat-treated synthetic Hematinite.
