Round Brilliant Cut Solitaire Stud Earring

This item is a single solitaire stud earring featuring a colorless, round brilliant-cut gemstone. The stone is held in a classic four-prong basket setting crafted from a silver-toned metal, likely white gold, platinum, or sterling silver. The gemstone measures approximately 5mm to 6mm in diameter, suggesting a weight of roughly 0.50 to 0.75 carats if it were a natural diamond. The cut appears to have standard faceting designed to maximize light return and internal fire, though the photograph shows some surface dust and smudging that slightly obscures the stone's clarity. Based on the visible facet meets and light dispersion, the stone could be a diamond, lab-grown diamond, or a high-quality simulant such as cubic zirconia or moissanite; a professional thermal conductivity test would be required for definitive identification. The metal prongs show rounded tips, common in contemporary jewelry manufacturing. There are no visible maker's marks or metal fineness stamps on the front-facing portion of the earring, which is typical as such marks are usually located on the post or the butterfly backing (not visible here). The condition appears to be fair to good, with no missing prongs or significant structural damage visible, though the metal exhibits a slight dullness suggestive of surface oxidation or standard wear from use. The style is timeless and minimalist, fitting a modern aesthetic that has been popular from the late 20th century to the present day.
