The Royal Purple Heart The heart-shaped, carat, Fancy Vivid Purple, clarity Royal Purple Heart diamond is the largest Fancy Vivid Purple diamond known to exist. The stone emanates from Russia and was cut by the Julius Klein Diamond Corporation.
The Heart of Eternity was found in a mine in South Africa and it has a “fancy vivid blue color”, making it an extremely rare diamond. Apparently, the blue color is given by impurities of boron and most of the gems are not entirely blue.
