About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1548493517. Listed at 4 retailers as of October 29, 2026, with prices from £21,681 to £32,160, a £10,479 spread on the same certified stone. MOH London lists it at £32,160. 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.
