Ring in the style of an Art Deco emerald-cut halo ring

This item appears to be a cocktail-style ring featuring a central dark gemstone, possibly an onyx or black spinel, though the material remains unverified without physical testing. The center stone is an emerald-cut or radiant-cut rectangular gem, held in place by four corner prongs. Surrounding this central stone is a halo of small, clear melee stones, which are stylistically consistent with crystals, cubic zirconia, or small diamonds; these are set into a metallic frame with a milgrain-textured edge. The shoulders of the band are also accented with small clear stones, tapering into a yellow-tone metal band. While the metal has a gold-colored finish, its specific composition (e.g., gold plating vs. solid alloy) is not visible. There is some slight lint and surface dust visible on the velvet display box, but the ring itself appears to be in good cosmetic condition with no obvious chips to the stones or significant loss of plating in the current view. No maker's marks or hallmarks are visible in the photograph; thus, the attribution remains hypothetical and based entirely on visual style.

Based on my visual examination of the provided image, I have evaluated this cocktail ring designed in an Art Deco aesthetic. The ring features a central emerald-cut dark gemstone, possibly onyx or black spinel, surrounded by a halo of clear melee stones. Based on what I can see, the metal exhibits a yellow-tone finish, though I cannot verify from a photo whether this is solid gold, gold-fill, or a plated base metal. The clear stones exhibit a sparkle consistent with common stimulants such as cubic zirconia or crystals, but physical testing would be required to rule out small natural diamonds. My estimate of $50-$150 is based on the hypothesis that the piece is a contemporary fashion or 'boutique' item rather than a vintage fine jewelry piece or a designer-signed work. This value is supported by the visible condition, which shows no obvious hallmarks or maker's marks, and the stylized milgrain edging often seen in modern mass-produced tributes to Art Deco. In the current secondary market, there is steady demand for 'in the style of' Art Deco jewelry, though prices for unauthenticated or non-precious costume pieces remain modest. To confirm a higher valuation, an in-person examination by a gemologist would be necessary to identify the stones and verify the metal's purity via acid or XRF testing. If physical inspection revealed the materials to be high-carat gold and natural gemstones, the value could increase significantly to the $600-$900 range. Conversely, if identified as a common costume reproduction with base metal and glass, the value would likely fall below $30.
