Pair of Round Cut Black Gemstone Stud Earrings

This item consists of a pair of stud earrings featuring round brilliant-cut black gemstones, likely black diamonds, spinels, or onyx, estimated at approximately 1.0 to 1.5 carats each based on their scale relative to the fingertips. The stones are secured in four-prong basket settings made of a white-colored metal, such as sterling silver, white gold, or platinum. The metal displays a bright, polished finish with no immediate signs of heavy oxidation or tarnish, suggesting high-quality plating or a noble metal composition. The gemstones exhibit a high luster and sharp facet edges, with one stone reflecting a distinct blue light, which could indicate a specific treatment, a coating, or the reflection of nearby ambient light. Physically, the studs appear to be contemporary in style, characterized by a minimalist aesthetic that emphasizes the stones over the metalwork. The earrings are held between fingers against a white fluted plate/surface, showing their small, portable scale. No structural damage is visible; the prongs appear symmetrical and intact, firmly gripping the girdles of the stones. There are no visible maker's marks or hallmarks in this view, though they would typically be found on the earring posts or friction backs. The overall craftsmanship appears consistent with modern commercial jewelry production.
