Created in the 1960s, this Van Cleef & Arpels Paris knot brooch is composed of 18K gold, platinum and diamonds. The brooch is designed as multiple coils of 18K gold ropetwist accented by lines of round brilliant-cut diamonds. An unusual Van Cleef & Arpels abstract design from the mid-century, this dynamic brooch combines the firm's signature 18K gold ropetwist threads with radiant diamonds.
