About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded J colour (near-colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6552142458. Listed at 4 retailers as of November 1, 2026, with prices from $18,644 to $24,210, a $5,566 spread on the same certified stone. Yorxs lists it at $24,210. 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.
