The 10.38-carat “Marie-Thérèse Pink Diamond,” which may have been once owned by Marie Antoinette achieved more than $13.9 million (including buyer’s premium), nearly double its high estimate at Christie’s New York Magnificent #Jewels #auction on Tuesday. Its hammer price was $11.8 million. The fancy purple-pink modified kite brilliant-cut #diamond has passed through French, Bavarian and Austrian imperial and royal families. In addition to its royal provenance, the gem was mounted on a ring created by renowned Franco-American jewelry artist, JAR. The #pinkdiamond was believed to be in a group of jewels that #MarieAntoinette entrusted to her coiffeur on the eve of her failed escape from Paris in 1791, hoping to one day reclaim them, Christie’s said in a previous statement. These jewels were passed down to her only surviving child, Duchess Marie Thérèse de Angoulême, and later to her niece, Duchess Marie Thérèse de Chambord. Tap the link in our bio to read more.
