Yellow Gold Pendant Necklace with Synthetic Ruby and Octagonal Tag

This piece of jewelry is a yellow gold necklace featuring two distinct hanging elements: a circular gemstone pendant and an octagonal textured metal tag. The primary pendant is bezel-set with a vibrant, round-cut synthetic ruby of a deep pinkish-red hue, surrounded by a scalloped or gear-like gold border that includes small white accents, likely seed pearls or white enamel, though some appear missing or degraded. The pendant is suspended from a delicate yellow gold box or anchor-style chain. Attached to the opposite end of the visible chain segment is a flat, octagonal gold tag featuring embossed Chinese or East Asian characters against a textured, sandblasted background. The craftsmanship indicates a commercial or mid-century production, possibly of 14k or 18k gold given the rich yellow color characteristic of high-karat Asian jewelry. Condition-wise, the piece shows visible signs of age and wear; the metal surfaces exhibit minor scratches and patina, and the decorative border around the central gemstone appears to have lost several of its small white inset elements. The chain is secured with a standard spring ring clasp. The overall style suggests a personalized or commemorative piece from the mid-to-late 20th century.

Based on my visual examination of this yellow gold necklace, I estimate its fair market value between $450 and $650. The piece features a vibrant round-cut synthetic ruby in a decorative bezel, paired with an octagonal tag displaying East Asian characters. The rich yellow hue suggests a high karat weight, likely 18k or 22k gold, which is typical for commemorative jewelry of this style. The condition is fair; the chain appears intact, but the pendant border shows significant loss of the white decorative insets, which impacts the aesthetic value. The market for mid-century Asian gold jewelry remains stable, primarily driven by the intrinsic metal value and the cultural significance of the inscribed characters. However, as it contains a synthetic gemstone and shows wear, it lacks the rarity a natural stone would provide. This valuation is based on visual data alone and assumes a total gold weight of approximately 4-6 grams. A definitive appraisal would require a physical inspection to conduct a specific gravity test or acid test to confirm the gold karat. Furthermore, I would need to examine the stone under 10x magnification to confirm the absence of natural inclusions and verify the setting stability. Provenance or a manufacturer's hallmark would also assist in refining the production date and origin.
