About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5566031006. Listed at 8 retailers as of October 27, 2026, with prices from $48,805 to $81,829, a $33,023 spread on the same certified stone. MOH London lists it at $81,829. 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.
