A diamond tiara once owned by Nancy Astor sold for £889,400 at an auction in May 2024. The tiara, a notable piece of jewelry, was acquired by Lord Waldorf Astor in 1930 and had not been on the market since then. This auction marked the first time the tiara was available for public purchase. The tiara is a Cartier piece, featuring turquoise and diamonds. It is historically significant as it was worn by Nancy Astor, the first woman to take a seat in the House of Commons. Astor, who was American-born, was elected in 1919 to represent Plymouth Sutton and held the seat until 1945. The tiara is known to have been worn to the premiere of the Charlie Chaplin film "City Lights." Nancy Astor's legacy as a pioneering figure in British politics is well-documented. Her election to Parliament in 1919 was a landmark event, symbolizing the growing role of women in public life. The sale of her tiara at auction highlights the enduring interest in historical artifacts associated with significant figures. The auction house confirmed that the tiara fetched £889,400, reflecting its historical and cultural value.
