Cushion-Cut Halo Diamond Engagement Ring

This is a contemporary-style engagement ring featuring a central cushion-cut gemstone, likely a diamond or high-quality simulant, which is approximately 0.75 to 1.00 carat in size. The center stone is bordered by a square-shaped halo of smaller round-cut melee stones, designed to enhance the visual scale and brilliance of the primary gem. The setting appears to be a white metal, possibly 14k or 18k white gold or platinum, though the heavy patina and visible tarnish on the undersides suggests it could be sterling silver with rhodium plating. The shank features a split-shoulder design, which is also pavé-set with small round stones that extend halfway down the band. The construction features a four-prong basket for the central stone and shared-prong settings for the halo and side stones. Regarding condition, there is noticeable surface grime and darkening in the crevices of the setting, which may indicate silver oxidation or accumulation of dirt and oils, requiring a professional ultrasonic cleaning. The style reflects a modern aesthetic popular from the early 21st century to the present. There are no maker's marks visible from this top-down perspective, but such hallmarks would expectedly be found on the interior of the band.
