About this 5.66ct natural cushion diamond

This 5.66ct natural cushion sits in the over five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6505211415. Listed at 11 retailers as of October 29, 2026, with prices from €260,374 to €461,947, a €201,573 spread on the same certified stone. MOH London lists it at €461,947. 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.
