Smoky Quartz Rectangular Pendant in Gold-Tone Setting

This item is a petite rectangular pendant featuring a faceted gemstone, likely smoky quartz or a similar dark colored glass, set in a yellow gold-toned metal mounting. The stone is rectangular-cut with visible internal facets that catch the light, displaying a translucent brownish-grey hue. The setting is a minimalist four-prong gallery style that transitions into a simple tapered rabbit-ear bale at the top. The metal surface exhibits a textured or slightly matte finish above the stone, suggesting a sandblasted or worn gold-plating over a base metal. In terms of dimensions, the pendant is approximately 1.5 centimeters in total length including the bale. Regarding condition, there is noticeable wear to the metal finish, particularly along the edges of the bale and the top of the gallery, revealing a duller underlying material consistent with vintage costume jewelry. There are no immediate maker's marks or gold purity stamps visible in the image, though they typically would be found on the reverse side or the bale. The style is characteristic of late 20th-century mass-produced jewelry, likely from the 1970s to 1990s. The craftsmanship is functional but indicative of affordable commercial manufacturing rather than high-end fine jewelry.
