Late Edwardian-Early Art Deco Diamond and Onyx Filigree Pendant Necklace

This unique antique diamond filigree necklace carries the heritage of two eras. The late Edwardian period gives way to the Art Deco as exemplified by the Greek key openwork design. Centered by an old mine cut diamond swinging freely in a black onyx donut and embellished with twinkling rose cut diamonds. This circa 1913 relic has a distinctive shape with great attention to detail.
