| Black Diamonds
The black diamond was once considered worthless and flawed but today, it is quickly becoming one of the most sought-after gems because of its unique and exquisite quality.
Compared with most coloured diamonds that characterize their dazzling hues because of chemical impurities that grow right within its crystal lattice, a black diamond provides smoky colourations from its mineral inclusions. These minerals are usually sulphide compounds, hematite, and magnetite. Higher concentrations of these inclusions generally cloud the stone, thus turning it into a rich or black colour. Since this tinting is typically caused by the inclusions instead of some impurities, a black diamond is usually opaque, although semi-transparent and translucent specimens are considered as extremely valuable. Natural black diamonds are particularly beautiful when set in platinum or white gold and with colourless diamonds to offset their colour. |
