Designed by the artist Louis Osman, the coronet was a gift from the Worshipful Company of Goldsmiths to the Prince's mother, Queen Elizabeth II.When the former King Edward VIII went into exile as the Duke of Windsor in 1936 following his abdication, he took with him the Coronet of George, Prince of Wales – a highly controversial act.In the centre of the arch is a monde (which is actually a gold-plated ping-pong ball)[5] engraved with the Prince of Wales's insignia by Malcolm Appleby, surmounted by a plain cross.Orbiting the monde are thirteen square diamonds set in platinum arranged as the constellation of Scorpio – the Prince of Wales's star sign.[6][10][11][12][13] B. J. S. Electroplating Co., a precious-metal electroformer's, was commissioned by the Worshipful Company of Goldsmiths to make a fibreglass-reinforced polyester mould of a wax model of the coronet that Louis Osman had made using a wooden template.
