A breathtaking aquamarine- and diamond-set brooch once owned by Princess Margaret is going under the hammer later this month.
Her Royal Highness was gifted the Cartier brooch, which dates back to 1932, in January 1947 by the Queen Mother, who bought it from the jeweller for about US$240.
The beautiful jewel will be sold by Dix Noonan Webb as part of the auction house’s Jewellery, Watches and Objects of Vertu sale on Tuesday, November 23.
Engraved with the letter “M” underneath Princess Margaret’s coronet, which is a small crown that signified her royal rank, the gem-set piece is an elegant piece of history that's likely to garner interest. In September, an Art Deco bracelet worn by the Countess of Snowdon for her official 19th birthday photograph taken by Cecil Beaton sold for ten times its estimated price.
