Round Brilliant Cut Gemstone Stud Earring

This item is a single stud earring featuring a round brilliant cut colorless gemstone, held in a four-prong setting. Based on visual inspection, the stone exhibits high dispersion and internal reflections characteristic of materials such as diamond, moissanite, or high-quality cubic zirconia. The stone appears to be approximately 1.0 to 1.5 carats in equivalent size. The setting is constructed from a polished white metal, likely 14k white gold, 18k white gold, or platinum, given the bright luster and lack of visible tarnishing common in silver. The prongs are delicately tapered, securing the girdle of the stone. The overall condition appears excellent with no visible chips or fractures to the crown or pavilion of the gemstone. Notable features include a 'hearts and arrows' style facet pattern visible under the surface, which suggests a modern precision cut. There are no immediate maker's marks visible from this angle, though such stamps are typically found on the earring post or the butterfly friction back (not shown). The style is a timeless, contemporary classic, often manufactured within the last 20-30 years. The craftsmanship is high-quality, indicated by the symmetrical alignment of the prongs and the clarity of the stone facets.
