Solitaire Pendant Necklace with Gold-Tone Chain

This item is a solitaire pendant necklace featuring a single, round faceted clear 'gemstone' suspended from a delicate gold-tone chain. The chain appears to be a fine curb or trace link style, showcasing a uniform yellow metallic color consistent with gold plating or a similar gold-colored alloy. At the back, there is an adjustable extender chain, allowing for variations in length. The clasp mechanism is not clearly visible but would typically be a spring ring or lobster clasp connected to the extender. The pendant itself consists of a round, brilliant-cut clear stone, which is likely a cubic zirconia, crystal, or glass imitation diamond, based on its visible brilliance and the common use of such stones in this style of costume jewelry. The stone is set in what appears to be a four-prong setting, integrated into a bail that allows it to slide along the chain. The metal surrounding the stone also exhibits a gold-tone finish that matches the chain. The overall construction suggests a mass-produced item. No specific maker's marks or signatures are discernible from the image, indicating it is likely a generic accessory. The item appears to be in good, wearable condition with no immediate visible signs of damage, heavy wear, or corrosion. The bright polish of both the metal and the stone suggests it is either relatively new or well-maintained. This style of necklace frequently dates from the late 20th century to the present, embodying a classic, minimalist aesthetic.
