Oh, Karl! You never cease to amaze us and now you have managed to create one of the most expensive collars in the world. This one-of-a-kind piece is designed with 40 carats of black diamonds, a 22.33-carat emerald centrepiece set in black rhodium-plated silver and black metallic leather. Priced at nearly $37,500 the collar will be on exhibit at the Vogue UK curated show Brilliant taking place at the Royal Hospital from June 27 until July 4.
