Black Onyx gemstones are chalcedony; it starts out grey and is dyed black in a process that has been used for centuries. The beads are then heat-treated, and the result is a jet black gemstone with uniform color. Romans used black onyx for glyptography, which is the art of carving into layers of stones, creating beautifully detailed cameos and intaglios.
