St Edward’s Crown - which is arguably the most famous crown jewel in the world. With over 400 precious and semi-precious gemstones, the crown weighs nearly five pounds. It includes 345 aquamarines, 37 topazes, 27 tourmalines, 12 rubies, seven amethysts, six sapphires, two jargoons, one garnet, one spinel, and one carbuncle. Experts have valued St. Edward’s Crown at 40 million dollars. St. Edward’s Crown was worn by Queen Elizabeth II during her precession in 1953, but since then has very rarely worn it. The reason for this is because of the weight, which the Queen said makes looking down when reading a speech nearly impossible.
