About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three 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 2566211562. Listed at 22 retailers as of November 4, 2026, with prices from £40,099 to £74,148, a £34,049 spread on the same certified stone. MOH London lists it at £74,148. 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.
