About this 3.18ct natural cushion diamond

This 3.18ct natural cushion sits in the three to five carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6237986950. Listed at 2 retailers as of October 30, 2026. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
