Vintage Gold-Tone Marquise Opal and Rhinestone Cluster Ring

This is a vintage-style fashion ring featuring a prominent cluster or 'sunburst' design. The central motif is composed of five marquise-cut white fire opal cabochons (likely synthetic or glass-based based on the uniform opacity) arranged in a tiered, arched formation. Adjacent to these stones is a secondary row of smaller, round brilliant-cut clear rhinestones or crystals, which are prong-set to add brilliance and contrast. The ring is constructed from a yellow gold-toned base metal, possibly gold-plated brass or a similar alloy common in late 20th-century costume jewelry. The band features an open, split-shoulder design that tapers toward the bottom of the shank. In terms of condition, there is visible wear to the gold plating along the edges of the prongs and the band, revealing a darker metal underneath indicative of frequent use. No maker's marks are clearly visible from this angle, but the assembly style is consistent with mass-produced costume jewelry from the 1970s through the 1990s. The craftsmanship is of standard commercial quality, focusing on aesthetic impact through the 'spray' of stones rather than high-end bench jewelry techniques.
