A 50-carat, rectangular-cut, D-color, potentially flawless diamond ring by Graff sold for $8.37 million at Christie’s New York Magnificent Jewels auction Tuesday. The buyer? Laurence Graff.

“This is the third time that I have owned this beautiful diamond and I am as thrilled today as I was the first time. Diamonds of this exceptional caliber have a life and legacy that carries on beyond us all,” Graff said in a statement after the sale. “This is one of the finest D-color diamonds in the world and I am delighted to have it back again.”

The diamond’s estimated sale price was $7-10 million. It sold for $167,400 per carat.

The final lot of the auction was a rare fancy reddish-orange diamond of 3.15 carats. The stone is the largest reddish orange diamond ever graded at the Gemological Institute of America. Exhibiting two of the rarest hues in the world of diamonds, the price soared beyond its low estimate of $700,000 to sell for nearly $2.1 million, setting a new world auction record for a reddish-orange diamond and a new per-carat record price of $666,200.

 Earlier in the sale, Christie’s realized a new per-carat record for a Kashmir sapphire at auction, with the sale of an 8.91 carat sapphire for $1.37 million, or $154,000 per carat (pictured left).

The day-long sale realized a total of $32.5 million, with sell-through rates of 84 percent by lot and 86 percent by value. This sale result, combined with results from Christie’s New York jewels auctions in April, June and October, brings the 2012 New York jewelry auction total to more than $163 million, the auction house estimated. The full 2012 total for the jewelry category will be announced in January 2013 as part of Christie’s annual corporate figures release.

For the year in New York, Christie’s said it sold 29 jewels over the $1 million mark, of which four jewels sold for more than $7 million. In April, Christie’s sold a collection of 17 Art Deco period jewels from the estate of the reclusive American copper heiress Huguette M. Clark. The sale realized $20.8 million and saw a new U.S. auction record achieved for The Clark Pink, the most expensive pink diamond ever sold at auction in the United States.
