Cocktail Ring with Purple Stone and Halo Setting

This item is a cocktail ring, likely electroplated gold or gold-filled, given its color and the overall aesthetic. The ring features a large, oval-cut central stone, which appears to be amethyst or a synthetic stone designed to mimic amethyst, judging by its deep purple hue with visible facets indicating a cut stone rather than a cabochon. This central stone is securely set, surrounded by a halo of smaller, round-cut colorless stones that sparkle, suggesting they are either diamonds, cubic zirconia, or another diamond simulant. These smaller stones are arranged in a sunburst or floral-like pattern, each individually prong-set, forming an ornate border around the main gem. The metal setting exhibits a rich yellow gold tone, and appears to be in good condition with no obvious signs of significant wear or tarnishing that would suggest poor care. The ring's band is visible and appears relatively slender, complementing the substantial size of the top cluster. The craftsmanship appears to be of a reasonable quality for costume or semi-fine jewelry, with stones evenly spaced and securely mounted. There are no visible maker's marks or signatures in the provided image. Based on its style, which features a prominent central stone surrounded by a halo of smaller stones, this ring could possibly date from the mid-20th century, perhaps from the 1950s to 1980s, when such elaborate cocktail rings were popular. The bright, uniform gold tone suggests it is not an antique piece, but rather a vintage item. There are no obvious signs of damage, such as missing stones, bent prongs, or significant scratches, indicating it has been well-maintained or is relatively new.
