New York, NY--A 10.38-carat Fancy Purple-Pink diamond with documented ties to French royalty sold for more than $13.9 million at Christie’s Magnificent Jewels auction in New York. The diamond, known as the Marie-Thérèse Pink, was graded by the Gemological Institute of America (GIA) and accompanied by a gemological report.

According to GIA’s update, the diamond was among over 30 significant jewels evaluated ahead of the auction. The Marie-Thérèse Pink was cut in a modified kite brilliant style and likely originated in India in the mid-1700s. GIA’s evaluation confirmed the diamond’s color origin and internal characteristics.
According to the report, the stone is believed to have passed from Queen Marie-Antoinette to her daughter, the Duchess of Angoulême, and later to her niece, the Duchess of Chambord.
Christie’s had estimated the ring to be worth between $5 million and $7 million. The final sale exceeded that range. The current setting, designed by jeweler JAR, features a fleur-de-lis motif in blackened platinum.
GIA’s Executive Vice President Tom Moses stated in the report that the institute’s role is to record the gemological and historical properties of notable stones. The report noted that the Marie-Thérèse Pink is one of the few examples of its kind, especially following the closure of major colored diamond sources such as Australia’s Argyle Mine.
