Solitaire Diamond or Cubic Zirconia Stud Earring

A single solitaire-style stud earring held between fingers for scale. The earring features a clear, brilliant-cut gemstone - likely a diamond or cubic zirconia - mounted in a four-prong setting. The metal appears to be a white-tone alloy, such as white gold, platinum, or sterling silver, though no hallmark is clearly visible in the low-resolution image. The gemstone is approximately 0.10 to 0.25 carats in size. The earring is secured with a standard friction post and a butterfly backing (clutch), which shows some minor signs of oxidation or wear consistent with use. The construction is a classic minimalist design, characteristic of contemporary fine jewelry from the late 20th to 21st century. The clarity of the stone appears high under ambient lighting, though a definitive appraisal of the stone's authenticity or grade would require loupe inspection for inclusions. The overall condition is good, with no visible bending to the post or missing prongs. The earring is accompanied by a secondary item in the shot: a simple, wide metal band worn on the finger, made of a similar white-toned metal with a matte or slightly worn brushed finish.
