Single Solitaire Diamond Earring Stud

This item is a single solitaire stud earring, consisting of a colorless faceted gemstone, likely a diamond based on its brilliance and cut, mounted in a yellow gold-toned metal setting. The gemstone is square-shaped, characteristic of a Princess cut, and appears to be approximately 0.10 to 0.25 carats in size. It is held securely by a classic four-prong basket setting that elevates the stone to maximize light entry and sparkle. The prongs are integrated into a post assembly, though the butterfly backing is not visible in the frame. The yellow gold metal displays a polished finish with no immediate signs of heavy tarnishing, suggesting a higher karat gold such as 14k or 18k. Regarding condition, the stone appears intact without visible chips to the crown or table, although a microscopic evaluation would be required for a definitive clarity and color grade. The setting shows minor signs of surface wear consistent with regular use. The overall design is minimalist and contemporary, reflecting a timeless style likely manufactured within the last 20 to 30 years. Quality is indicative of standard fine jewelry craftsmanship found in commercial jewelry retail outlets.
