One of the rarest types of gemstone in the world is the red diamond. To date, there are less than fifty red diamonds known in existence. A reddish-orange 3.15-carat fancy red diamond will be offered at Christie’s Sale of Magnificent Jewels on December 10th. This diamond is a circular cut diamond with a S12 clarity. In addition, it is even more so rare for a red diamond of over 1.0-carat to exist. Christie’s has estimated that the diamond will sell for up to $1.2 million.
The value of a red diamond is dependent on the intensity of color. The strong the hue, the more valuable the red diamond; a faint red diamond will be a much less value than a fancy vivid red hue. The high color saturation of the red-orange color is what will give this diamond a high price tag. Researches attribute the stark red color to the small quantities of nitrogen or hydrogen introduced during the development process, creating a unique crystal lattice structure.
Another highlight at the upcoming auction is a 50.01-carat rectangular cut diamond in platinum ring by Graft with two baguette-cut diamond accents that is estimated to sell at $10 million. Brand name jewelry sellers will be also sold at the auction, such as Tiffany & Co., Van Cleef & Arpels, Cartier, and more.
