Chromite Value, Price, And Jewelry Information ...

Comments: Chromite is shiny and black, and makes a curious-looking cabochon with no special attraction. Occasionally, a cabochon has a reddish color. The stones have little value because the material is extremely abundant but are cut as curiosities only. Sometimes weakly magnetic. Name: In allusion to the composition.

Chromite | Physical

Chromite | Physical

Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4. It is belonging to the spinel group. Chromite is the most important ore of chromium. Crystals are uncommon, but when found they are octahedral. Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granules.

General : Chromite/Magnetite From Shetland

This specimen is allegedly chromite from an unspecified Shetland locality. It is however strongly magnetic and has a black streak. Some of the other pieces have small crystals of a "mica" attached (but I haven't examined them in person). The white material is apparently calcite but I don't have HCl to hand.
