Diamond[a] is a gemstone formed by cutting a raw diamond. Diamonds are one of the best-known and most sought-after gems, and they have been used as decorative items since ancient times.
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond as a form of carbon is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of electricity, and insoluble in water.
Diamond is the only gem composed of one single element: carbon. Most diamonds formed more than a billion years ago, deep in the earth’s mantle. The human contribution to a diamond’s beauty is a well-executed cut. Clarity grades assess the number, size, relief, and position of inclusions and blemishes. The less color, the higher the grade.
Diamond is the only gem made of a single element: It 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 the diamond’s essential chemistry. Some trace elements can influence its color or crystal shape.
