Fashion Ring with Crescent Moon or Oval Center and Halo Setting

The item is a women's fashion ring, worn on the index finger of a hand that appears to be of an older individual, given the visible wrinkles and apparent age spots. The ring features a distinct central element resembling a crescent moon or irregular oval shape, which is a light, possibly iridescent material such as mother-of-pearl or a similar nacreous substance. This central piece is surrounded by what appears to be a halo setting of numerous small, faceted clear or light-colored stones, likely rhinestones or cubic zirconia, which are set relatively close together. The metal of the ring appears to be a gold tone, suggesting it could be brass, gold-plated, or a lower karat gold alloy, though its exact composition cannot be determined without closer inspection. The overall design features an intricate pattern around the central element, with additional decorative elements or smaller stones extending outwards, giving it a somewhat sunburst or floral appearance. The setting style for the surrounding stones appears to be pave or bead set, contributing to a sparkling effect. The ring's band is partially visible and appears to be a simple, solid band. There are no visible condition issues such as missing stones or significant wear on the metal, though the resolution of the image makes it difficult to assess minor abrasions or tarnishing. There are no discernible maker's marks or signatures visible from this angle. The style suggests it could be a piece from the mid-20th century to contemporary, possibly a costume jewelry piece due to the apparent materials. The craftsmanship appears to be standard for fashion jewelry, with attention to detail in the setting of the numerous small stones.
