What is a Diamond?

Diamond is the only gem made of a single element: carbon. Diamond is typically about 99.95 percent carbon. The other 0.05 percent can include one or more trace elements, which are atoms that aren’t part of a diamond’s essential chemistry. Some of them can influence its color or shape. Formation conditions also help determine a mineral’s identity.

Diamond forms under high temperature and pressure conditions that exist only within a specific depth range beneath the earth’s surface.
