Black diamonds are a wonderful option as small stones under 0.10ct, to be set into wedding rings or eternity bands. With their beautiful opaque appearance, black diamonds create a very sleek contemporary look. Channel setting a row of princess or baguette diamonds against a wall of white gold creates a stunning modern clean look. One famous black diamond engagement ring, is the ring Sarah Jessica Parker’s character’s ‘Carrie Bradshaw’ received  in the ‘Sex and the City’ movie. Considered a style icon in modern popular culture, this ring saw a surge in the popularity of black diamonds in jewellery.

Black diamonds were first discovered in the 1800s. Most black diamonds are mined in Brazil, but are also found in Africa and Australia. They are also known as ‘Carbonados’ meaning burned or carbonized in Portuguese. The majority of black diamonds on the market are heat treated although it is possible to source natural black diamonds.

Natural black diamonds get their colour from graphite inclusions. These graphite inclusions make the structure of the natural black diamond more fragile than an enhanced one. This fragility makes it more difficult to cut and polish and therefore makes them much rarer to come by than an enhanced stone. Enhanced black diamonds are treated with radiation to give them their colour. Their natural colour before being enhanced is actually dark green. The benefits of an enhanced black diamond compared to a natural black diamond is that they are stronger as they do not have the graphite inclusions that are found in a natural black diamond.
