About Jet

Jet

Jet is one of the four gemstones on earth that are organic in nature, the others being pearl, amber, and diamond. Like diamond, jet is a carbon compound, but it is not as old. The hardness of jet varies, as does its natural finish, which ranges from a soft and lustrous black to a metallic surface much like hematite. Prized in the past for its carvability and light weight, jet has been a favorite of jewelers for many centuries.
