Beautiful vintage engraved chain necklace with a toggle closure, in gunmetal gray. Not marked but the style of chain, and the
overall look, is characteristically French, and it came from an estate with other signed French jewelry. Probably 1970s.
Perfectly on trend; oversized chains and gray tones are key current looks.
Wearable length is 15 1/2 inches. Just over 5/8 inch wide. Excellent condition. Photos enlarged to show detail.
