Black diamonds: what are they?
Black diamonds have a dark, velvety lustre that is entirely different from the sparkle of white diamonds. They have become popular in men's jewellery and with anyone who wants a more modern look.
Why are they black?
Black diamonds get their colour from dense inclusions of dark minerals, such as graphite. Many black diamonds on the market have also had their colour enhanced by treatment, such as heating. Ask us if you would like to know more about the stones in a particular piece.
Lustre rather than sparkle
A white diamond is cut to reflect light and create sparkle. A black diamond does not let light through in the same way and is instead cut for a glossy, almost metallic surface. The result is a discreet yet striking look.
Popular in men's jewellery
Their discreet look has made black diamonds popular in men's jewellery, such as wedding rings, eternity rings and tennis bracelets. They suit women who want something a little different just as well. Paired with black oxidised white gold, the look becomes even darker.
Caring for black diamonds
Black diamonds have the same hardness as other diamonds, but their inclusions can make them more sensitive to knocks. Avoid ultrasonic and steam cleaning, and have a jeweller check the setting now and then.
