Natasha Poonawalla's Rare Pink Diamond Ring
In a video shared on Instagram, Dhrumit revealed that the ring is known as the Marie-Thérèse Pink Diamond Ring. The exquisite piece has a rich history, as it once belonged to Queen Marie Antoinette. The ring's centrepiece is a 10.38K fancy purple and pink modified kite brilliant-cut diamond. It is surrounded by round diamonds and set in a blackened platinum band decorated with 17 diamonds.
According to Christie's, the central diamond dates back to the mid-18th century and was inherited by Duchess Marie-Thérèse d'Angoulême, the daughter of Queen Marie Antoinette. The ring remained part of the royal family's collection for many years until it was sold in 1996.
Later, renowned jewellery designer Joel Arthur Rosenthal, known as JAR, crafted a new band for the diamond. On June 17, 2025, the ring was sold at Christie's Magnificent Jewels sale in New York for $13,980,000 (approximately ₹1,25,10,83,959). The piece of French history fetched more than double its estimated price, exceeding the expected range of $3 million to $5 million.
