Kojis Platinum Diamond Tennis Player Brooch | Brimming with character, this brooch is a one-of-a-kind statement piece from antique purveyor Kojis. Crafted from platinum, it depicts an art deco-inspired tennis player holding a platinum racket and diamond tennis ball, while the body is made up of multiple single cut diamonds, varying in size. The player has a blue sapphires collar and hat, while the face and hand are fashioned from rubies. Wear it alone or team it with several other artisanal brooches and pins for a maximalist take on traditional formalwear.
