This piece is an antique revision made from reclaimed antique materials. This necklace was originally an antique platinum filigree brooch, handcrafted sometime during the Edwardian design period ( 1900-1920 ). The platinum pendant features a gorgeous Old European cut center diamond measuring approximately 0.85 carats. The pendant features many enchanting details such as an additional 16 diamond accents, hand engravings, fine filigree, and fine milgrain accents. During the restoration process the pin was removed and the brooch was fitted with two custom bales to accommodate the chain. The chain measures 16 inches in length and the brooch measures 2 inches in length. The chain features an easy to use lobster claw style clasp closure. The chain is 14k white gold.
