Diamond is a transparent, optically isotropic crystal with a refractive index of 2.417, a high dispersion of 0.044, and a specific gravity of 3.52.
In the late 18th century, diamonds were demonstrated to be made of carbon by the rather expensive experiment of igniting a diamond (by means of a burning-glass) in an oxygen atmosphere and showing that carbonic acid gas (carbon dioxide) was the product of the combustion.
In response to public concerns that their diamond purchases were contributing to war and human rights abuses in central Africa, the diamond industry and diamond-trading nations introduced the Kimberley Process aimed at ensuring that conflict diamonds do not becoming intermixed with the diamonds not controlled by such rebel groups.

The quality of a diamond's cut is widely considered the most important of the four Cs in determining the beauty of a diamond; indeed, it is commonly acknowledged that a well-cut diamond can appear to be of greater carat weight, and have clarity and colour appear to be of better grade than they actually are.
