In an Instagram video, Dhrumit revealed that the jewel is known as the Marie-Thérèse Pink Diamond Ring. The historic ring features a 10.38-carat fancy purple-pink modified kite brilliant-cut diamond at its centre, encircled by round diamonds and set on a blackened platinum band adorned with 17 diamonds.

According to Christie’s, the central diamond dates back to the mid-18th century. It was inherited by Duchess Marie-Thérèse d’Angoulême, the daughter of Queen Marie Antoinette, and remained within the French royal family for generations before being sold in 1996.
