Oval Black Gemstone Sterling Silver Pendant Necklace

This jewelry piece consists of a sterling silver snake chain holding an oval-shaped pendant. Based on the provided context, the metal is .925 sterling silver, which is indicated by the bright, lustrous white-metal finish of both the chain and the pendant setting. The pendant features a large, multifaceted oval-cut gemstone, appearing black or very dark blue (potentially onyx, spinel, or sapphire), secured in a four-prong setting. Surrounding the center stone is an ornate halo border with beaded or milgrain detailing, a hallmark of vintage-inspired or Art Deco Revival styles. The bail of the pendant is elongated and also features textured detailing that matches the halo. The snake chain is a smooth, round, flexible link style that provides a modern contrast to the more traditional pendant design. The craftsmanship appears to be of commercial high quality with clean symmetry in the faceting and setting. Condition appears excellent with no visible tarnishing, chips to the stone, or kinks in the chain, suggesting either a contemporary manufacture or a well-maintained piece from the late 20th to early 21st century.
