United Kingdom—St. Edward’s Crown

St. Edward's Crown, possibly the most renowned crown gem in the world, is ranked first on our list of the most expensive crown jewels in the world. Scepters with a cross or dove, orbs, swords, spurs, rings, columbium sindonis, and other items are included in the collection of jewels. The crown is distinguished by the world-famous and unrivaled 105-carat Koh-i-Noor diamond, which was acquired in India. The crown weighs approximately five pounds and contains over 400 precious and semi-precious jewels. 345 aquamarines, 37 topazes, 27 tourmalines, 12 rubies, seven amethysts, six sapphires, two jargoons, one garnet, one spinel, and one carbuncle are included in the piece. St. Edward's Crown is estimated to be worth $40 million by experts. Queen Elizabeth II wore St. Edward's Crown during her coronation in 1953, but she has only worn it a few times since then. The reason for this is the weight, which, according to the Queen, makes looking down during a speech practically impossible.

Estimated Value: $40 million
