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 VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5231759590. Listed at 15 retailers as of October 30, 2026, with prices from $17,788 to $28,787, a $10,998 spread on the same certified stone. MOH London lists it at $28,787. 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.
