perfect 100 carat diamond sotheby's new york auction magnificent jewels 2015March 5, 2015: Sotheby’s has unveiled an extraordinary 100-carat perfect diamond in a classic Emerald-cut. The 100.20-carat, D color, Internally Flawless, Type IIa stone will highlight Sotheby’s Magnificent Jewels auction in New York on April 21, 2015, when it is estimated to sell for US$19-25 million. 

Diamonds of this exceptional quality are incredibly rare, and are considered ‘perfect’. The present example joins an elite group of just five comparable-quality diamonds over 100 carats that have ever been sold at auction worldwide. 

The original rough – weighing over 200 carats – was mined by De Beers in southern Africa. The current owner spent over one year studying, cutting and polishing the rough diamond to deliver the spectacular stone. Gary Schuler, Head of Sotheby’s Jewelry Department in New York, commented, “The color is whiter than white, it [the diamond] is free of any internal imperfections, and so transparent that I can only compare it to a pool of icy water. It is the first true emerald-cut diamond over 100 carats to be offered at auction – the most classic of cuts, quietly elegant and very contemporary.”
