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 of 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 blue diamonds 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 27ct diamond as part of the  “The Beers Millenium Jewels Collection”. Besides these two places they are also found in very small quantities in the Golconda Mine in India.

It was found in India early in the 17th century, travelled half the world, then it was stolen from the French Crown Jewels in 1762 during the French Revolution. Afterwards it was bought by Henry Philip Hope in 1839 and has been in the hands of many different owners before it was donated by Harry Winston Jewelers to the Smithsonian Institution in Washington DC  in November 1958. The diamond has a bad reputation of bringing misfortune to many of the owners it had.

The largest cut blue diamond is 70ct and it is called “Idol’s eye” and was originally part of an ornament in a Benghazi temple, but later came into the hands of Mrs. May Stanton after World War II.
