The term white diamond is an alternative name for transparent colourless diamonds; as sold on every High Street. The term white diamond is used in trade to distinguish “ordinary” diamonds from naturally coloured diamonds. Naturally coloured diamonds are found in all colours; but they are very rare and expensive.
Colored diamonds have been smashing sales records at auction houses the past few years, but here’s one that hasn’t gotten a lot of press: the white diamond. Yes, white! Get ready to fall in love with this remarkable beauty. Their hues can range from colorless (like a drop of pure water) to having tints of light yellow, light brown or gray. The rarity, and therefore the value, of these diamonds is based in part on how closely they approach colorlessness. All things being equal, the more colorless the diamond, the more rare and expensive it is.
White diamonds are also sometimes described as “opalescent,” because of the flashes of color that can be seen when viewing the diamond face-up.
