Vintage 10K Gold Cocktail Ring with Large Faceted Gemstone

This item is a vintage cocktail ring featuring a prominent, large, faceted gemstone set in a 10K gold band. The gemstone appears to be a smoky quartz or a similar yellowish-brown to dark brown colored stone, meticulously cut in what seems to be an emerald or step cut, maximizing its surface area and brilliance. The stone is quite substantial in size, dominating the top of the ring, and exhibits good clarity with a rich, consistent color saturation. The setting is a classic multi-prong style, specifically a six-prong basket design, crafted from yellow gold that is visibly marked as 10K. The individual prongs securely hold the large stone, rising quite high from the finger, indicating a bold 'statement' piece characteristic of cocktail rings. The band itself is a simple, polished gold shank, tapering slightly towards the bottom. The gold shows a warm, lustrous finish, though minor surface wear consistent with age and use (fine scratches, slight tarnishing) may be present but is not clearly discernible in the provided image. The overall craftsmanship suggests a well-made, solid piece of jewelry from potentially the mid-20th century (e.g., 1940s-1970s), a period known for large, impressive rings. There are no visible repairs or significant damage evident, and the stone appears to be intact without major chips or cracks. The design emphasizes the gemstone, a common practice in cocktail jewelry.
