THE PERFECT PINK – $23.2 MILLION
According Christie’s website, in its 244 years history, only 18 pink diamonds over 10 carats have appeared. And none of them had the Fancy Intense Pink shade of the Perfect Pink, which at 14.23 carats, is in ‘a class of its own’. Those having a nearby shade hardly weigh more than 0.2 carats. Not only that, the Perfect Pink has no secondary color in it. Pink diamonds usually have color modifiers like grey, orange or purple. It has a clarity grade of VVS2 (Very Very Slightly Included) due to light internal blemishes which are common in such diamonds. In December 2009, it was sold in Hong Kong for USD 10,776,660 to an anonymous bidder.
