Three-Stone Diamond or Cubic Zirconia Ring

The item is a finger ring, likely crafted from white gold, platinum, or sterling silver, given its silvery-white metallic sheen. The design features a prominent three-stone setting, often referred to as a 'trilogy' or 'past, present, future' style. The central gemstone appears to be a square or princess cut, while the two flanking stones are also square or princess cut, but slightly smaller than the center. All three main stones exhibit significant sparkle, suggesting they are either diamonds or high-quality cubic zirconia. The surrounding stones in the halo and along the band are smaller, round brilliant-cut accents, set into the metal, likely in a pave or channel setting, extending down the shoulders of the band. The metal band itself appears to be of moderate thickness. The ring is worn on the ring finger of a person with fair skin, and the hand is resting against a blue denim fabric, possibly jeans. The overall lighting is heavily influenced by a strong green light source, which causes a green luminescence or reflection on the gemstones, making it difficult to ascertain their true color without this external light interference. There are no clear visible markings or engravings, and no overt signs of damage or wear are discernible from the image, aside from a slight natural patina or dullness that might be present on the metal, typical of worn jewelry. The craftsmanship appears to be of good quality, with stones well-set and a classic, elegant design. The estimated age depends on the materials; if diamonds, it could be a contemporary engagement or anniversary ring; if cubic zirconia, it might be a fashion ring, likely from the late 20th or early 21st century.
