Catherine premiered Kiki Lola Blue Topaz Hoop Earrings in July 2012 at a London Olympic reception held at Buckingham Palace. At that time the earrings were a bespoke piece that later on were added to Kiki’s Lola Collection. These stunning earrings feature Blue Topaz and Diamond hoops in 18ct White Gold. The earrings were actually a double hoop – a large ring of alternating blue topazes and diamonds suspended from a much smaller, diamond-studded hoop. They are currently retailing for £2,666.67.
