Round Cut Stud Earring Appraisal

Round Cut Diamond or Cubic Zirconia Stud Earring

The item in question is a single stud earring, characterized by a round, brilliant-cut gemstone set within a circular, possibly prong-free or bezel-like metal setting. The gemstone appears clear and colorless, exhibiting facets that reflect light, suggesting it could be a diamond or a high-quality cubic zirconia (CZ). The setting material is a light-colored metal, likely white gold, platinum, or sterling silver, given its silver-tone sheen. The overall diameter of the stud, including the setting, appears to be approximately 5-7 millimeters based on its scale in relation to the average adult finger holding it. The setting design favors a smooth, rounded edge around the gemstone, which helps protect the stone from chipping and snagging. There are no visible prominent prongs, indicating either a bezel setting, a flush setting, or very subtle prongs. The back of the stud, which would typically contain the post and an identifying mark, is not visible. The condition appears to be excellent, with no immediate signs of wear, scratches, or damage to either the stone or the metal. The reflection and sparkle indicate a clean and well-maintained piece. Without clearer visibility for hallmarkings or further testing, the exact material of the stone and metal cannot be definitively confirmed, but the craftsmanship suggests a commercially produced piece of fine or fashion jewelry, likely from the late 20th or early 21st century given the common use of similar designs in modern jewelry. The item's primary function is as an ornamental adornment for the ear.
