Sotheby’s calls it “arguably the most desirable pink diamond to appear at auction in recent years,” and thinks it will fetch from $12.8 million to $15.4 million, which would set a per-carat record price for a pink diamond.
The stone was mined by De Beers and cut in New York City from a 19.54 ct. rough.
“Internally flawless clarity…is extremely rare in pink diamonds and virtually unseen in any significant pink diamond of fancy vivid or fancy intense color grading ever sold at auction,” said the auction house.
With its color, one of the most beautiful and concentrated shades of pink in diamonds, combined with its exceptional clarity, the diamond will command the highest per-carat pre-sale estimate for any pink diamond to date. The record price per carat for a fancy vivid pink diamond is more than $2.1 million per carat set by a 5-carat diamond sold in Hong Kong in January 2009 for more than $10.7 million. Many pink diamonds have set auction records in recent years, including the Graff Pink, a 24.76 ct. fancy intense pink, which was purchased by Laurence Graff in Nov. 2010 for $46 million.
What makes pink diamonds pink? Unlike other colored diamonds, the pink color is not due to foreign trace elements trapped inside the diamond's structure. Pink diamond are thought to be the result of changes to the electron structure, called “plastic deformation”. While the crystal is growing, intense pressure changes the lattice structure of the diamond, producing what we see as a spectrum of pinks, from pastels to deep purple-reds.
