Blue diamonds

basic facts about blue diamonds

Blue diamonds thank their color to the presence of boron in the crystal structure. Even in very small concentration like only a few atoms in a million already an attractive color appears. As the concentration gets higher, then off course the color of the diamond will become more intense. If blue diamonds are illuminated with ultra violet light they will display a very specific blue glow, unseen with other colors of diamonds.

Currently they are found in very few mines around the world. They are found in Rio Tinto’s Argyle mine in Australia and in the Cullinan mine in Pretoria, which is also known to have produced the Vivid blue Heart of Eternity, a 27  ct.diamond as part of the  ‘The Beers Millenium Jewels Collection’. Besides these two places they are also found in very small qualtities in the Golconda Mine in India.
