Single Solitaire Diamond Earring Stud

This is a single solitaire stud earring, featuring a traditional round brilliant-cut colorless gemstone, likely a diamond or a cubic zirconia, set in a yellow gold mounting. The gemstone is held securely by what appears to be a four-prong or six-prong basket setting, which is a classic design intended to maximize light entry into the stone for enhanced brilliance. The metal exhibits the characteristic warm, high-luster characteristic of yellow gold, likely 10k or 14k based on common jewelry manufacturing standards. The earring is small in scale, suggesting a dainty or minimalist aesthetic. Regarding condition, the metal surfaces show minor micro-scratches consistent with wear, though the gemstone appears clear without visible fracturing. There is no visible hallmark or maker's mark in the photograph, which would typically be located on the post or the butterfly clasp back (not pictured). The overall style is timeless and typical of late 20th to early 21st-century fine jewelry, prioritizing a clean and elegant presentation. The craftsmanship appears standard for commercial-grade jewelry, featuring symmetrical prongs and a polished finish.
