About this 10.78ct natural cushion diamond

This 10.78ct natural cushion sits in the over five 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 2235967122. Listed at 3 retailers as of October 31, 2026, with prices from $316,338 to $378,770, a $62,432 spread on the same certified stone. Fonder Diamond lists it at $378,770. 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.
