Vintage Platinum Diamond Necklace, Art Deco Platinum Filigree Necklace

Elegant Art Deco era diamond filigree necklace, 14k yellow gold base with platinum overlay. This beautiful necklace was originally a antique brooch that I converted into a new stylish modern style necklace. The beautiful filigree metal work is platinum and very clean, in excellent condition. This beautiful art deco piece now hangs from a 14k white gold 18" chain
