A “perfect” 100-karat diamond in a classic emerald cut sold for just over $22 million at auction on Tuesday.
The internally flawless D-color stone is the only classic emerald-cut white diamond of the highest color and clarity and over 100 karats to come to auction, according to Sotheby’s. The final price on Tuesday night was $22,090,000, including the buyer’s premium.
“This 100.20-karat diamond is the definition of perfection. The color is whiter than white. It is free of any internal imperfections,” Sotheby’s said prior to the sale, likening its transparency “to a pool of icy water.”
The diamond was mined in southern Africa within the last 10 years and weighed over 200 karats before it was cut and polished.
Only five “perfect” diamonds over 100 karats have sold at auction in the last 25 years, with a 118-karat oval-cut stone fetching $30.6 million in 2013. The record for any jewel is $46 million for a 24.78-karat emerald-cut pink diamond in 2010.
