The Arcot Diamond from the Golconda mine, a brilliant-cut, pear-shaped, D-colour stone weighing 17.21 carats, was one of two such diamond ear drops sent as gifts to Queen Charlotte (1744-1818), the wife of King George III, from the Nawab of Arcot. The diamonds were later acquired at auction by the Marquess of Westminster and subsequently mounted in the Westminster Tiara, which was worn at the coronation of Queen Elizabeth II. The diamond sold for $3,375,000.
