The 5 Ct Vivid Pink Up For Auction

Owned by a private collector, the stone is set in a ring by famed jeweler Graff and is estimated to sell for HK$ 39-55 million ($5-8 million or $1-1.6 million per carat).

Pink diamonds are extremely rare and thought to obtain their unique color from alterations in the atomic lattice of the diamond. Unlike other pink diamonds, the Vivid Pink displays no secondary color modifiers such as purple or orange often found in pink diamonds.

The current record for a pink diamond sold at auction is for a rectangular-cut fancy pink VVS2 diamond weighing 19.66 carats and sold at Christie’s Geneva in 1994 for $7.42 million ($377,483 per carat).

At $24 million, the most valuable fancy diamond ever sold at auction is the Wittelsbach blue diamond.
