If you follow along on my Instagram you'll know it's Tiara Tuesday again! The Bagration tiara - diamonds and pink spinels. The tiara dates to about 1810. Attributed to Fossin & Fils, a predecessor of the French jeweler Chaumet. It was purchased by the Russian Princess Katharine Bagration, heiress to Prince Potemkin and listed in the 1836 inventory of her jewels. Bought by the current Duke of Westminster for his bride to wear at their wedding in 1978.
