About this 2.5ct natural cushion diamond

This 2.5ct natural cushion sits in the two to three carat band, graded F 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 7478666046. Listed at 2 retailers as of October 30, 2026, with prices from £30,606 to £42,996, a £12,390 spread on the same certified stone. Diamond Quarter lists it at £42,996. 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.
