8. Emerald and Diamond Tiara
The emerald and diamond tiara was commissioned in 1900 by German Prince Guido Count von Henckel as a gift for his wife, Princess Katherina Henckel von Donnersmarck. The stunning diamond and emerald tiara was created with 11 extremely rare Colombian, emerald pear-shaped drops weighing in at about 500 carats, which were believed to have once belonged to Maharajah. The tiara is thought to be a part of the personal collection of Empress Eugenie. The tiara was sold through the Sotheby’s Magnificent and Noble Jewels sale for $12. 7 million, which is reportedly $2 million more that the estimated price.
