Carnelian Free Form Brown a compound of calciumCarnelian is a red variety of the mineral chalcedony, a fibrous variety of quartz that forms in masses rather than points. It may be solid, have agate banding, or form with quartz crystals. The red, orange, and brownish colors come from trace amounts of hematite and hydrated iron oxides suspended within it. Carnelian was carried by ancient travelers who believed it would protect them from death and guard against evil while they were away from home.
