Art Deco-Style Diamond Pendant Necklace

This is an elegant Art Deco-style pendant necklace featuring a curvilinear, openwork design. The pendant is crafted from a white metal, likely 14k or 18k white gold or platinum, and is suspended from a delicate silver-toned chain, possibly a wheat or Spiga style link. The pendant showcases a central larger round-cut stone, surrounded by multiple smaller round-cut accent stones, all appearing to be diamonds or high-quality diamond simulants. The stones are Pav-set and bezel-set throughout the geometric and scrollwork filigree. The pendant's silhouette is elongated, resembling a droplet or stylized pear shape with a decorative bail that is also encrusted with accent stones. The construction exhibits fine craftsmanship with milgrain detailing along the edges of the metalwork, a hallmark of Art Deco and Edwardian aesthetic revival. The overall condition appears to be excellent with no visible missing stones or significant scratches on the metal surface, suggesting modern production within the last 20-30 years. No visible hallmark is seen in the image, but the quality of the stone setting and metal finish indicates a high-end jewelry piece.
