Natural fancy pink diamonds are completely natural and caused by a process called
'plastic deformation' when pink graining is caused by a natural deformation of the diamond crystal while it is in a semi-solid state. Most fancy natural pink diamonds come from the Argyle mine in northwestern Australia. "... A pink diamond has long been considered one of the rarest colored diamonds." (source: S.C. Hofer, Pink Diamonds from Australia, 1985).
The seven natural color grades for natural fancy colored diamonds are, in ascending order, faint, very light, light, fancy, fancy intense, fancy vivid and fancy deep. Fancy vivid and fancy deep the most desired hues.
Red, purple and orange are the secondary hues found in natural fancy pink diamonds.
Today, the pink diamond is playing the role of Cupid among the colored diamonds. Ben Affleck purchased a 6.1 carat pink diamond ring for his engagement to Jennifer Lopez and David Beckham gave his wife, former Spice Girl Victoria "Posh" Adams a $1.8 million pink diamond apology ring following his public indiscretion.
Natural fancy pink diamonds come in all cuts, including princess, emerald, asscher, oval marquise, pear, radiant, heart and cushion, though round natural fancy pink diamonds are the most common.
