Marquise Cut Light Blue Stone Pendant with Accent Stones

This is an antique or vintage pendant, likely crafted in a white metal such as silver, white gold, or platinum, or perhaps a base metal with a rhodium or silver plating. The central feature is a marquise (or navette) cut light blue gemstone, possibly topaz, aquamarine, or a glass/crystal imitation, which is prong-set within a stylized, somewhat geometric frame. The main gemstone exhibits visible facets and appears to be slightly cloudy or has some internal characteristics, though this could also be surface wear. The frame's design could suggest an Art Deco or Mid-Century Modern influence, characterized by its clean lines and angularity. Flanking the central stone on either side are two smaller, round, faceted clear or slightly yellowish accent stones, which are also prong-set. These small stones could be diamonds, white sapphires, or clear zircons/glass. The metal setting shows some signs of wear, including minor scratches and possibly some tarnishing, especially visible on the prongs and around the edges of the frame. The bail, which connects the pendant to the chain, is integrated into the top of the frame design and appears sturdy. The chain itself is a curb link or similar type, also in a white metal, and shows consistent wear with the pendant. The craftsmanship, while appearing mass-produced, shows careful setting of the stones. There are no visible maker's marks or stamps in the provided images, making a definitive identification of the metal composition or exact age difficult without further inspection. The overall condition suggests it has been worn and cherished.
