Solitaire Diamond or Simulant Ring in White Gold or Platinum Setting

This item is a classic solitaire engagement-style ring featuring a round brilliant-cut colorless stone. The primary stone is held in place by a traditional four-prong or six-prong basket setting, though the specific prong count is slightly obscured by the focus. The metal appears to be a high-polish silvery-white alloy, consistent with 14k or 18k white gold, or possibly platinum. The band is a slender, rounded shank (D-shape) with a high-luster finish. While the stone possesses significant fire and brilliance, closer inspection toward the culet suggests potential inclusions or facets that could indicate a natural diamond, though a lab-grown diamond or high-quality cubic zirconia cannot be ruled out without spectroscopic testing. There are no immediately visible maker's marks or metal fineness stamps on the outer shank, which is typical for modern contemporary jewelry design where markings are placed on the interior of the band. The condition appears to be excellent with no visible warping of the band or chips to the stone's girdle, suggesting a relatively modern age, likely late 20th to early 21st century. The craftsmanship is clean and minimalist, focusing on maximizing light entry to the pavilion of the center stone.
