Rare 300-Carat Diamond Necklace from Queen Elizabeth II’s Coronation Hits the Auction Block

A rare 300-carat diamond necklace worn by a noble at Queen Elizabeth II’s coronation will be auctioned.

According to The Guardian, the necklace will be auctioned at Sotheby’s Geneva in November.

The necklace, made in the 18th century, consists of 500 diamonds connected in three rows with diamond tassels.

The Marquess of Anglesey family owned the necklace until the 1960s, and it was reportedly worn at Queen Elizabeth II’s coronation in 1953 and King George VI’s in 1937.

While there is no detailed record of the necklace’s origin, it is believed to have been made for royalty or high-ranking nobility about ten years before the French Revolution.

The necklace will be exhibited in London, Hong Kong, New York, Singapore, and Taiwan before being auctioned at Sotheby’s in Geneva. It is expected to fetch up to $2.8 million at the Geneva auction.
