About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded H colour (near-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 2556797124. Listed at 12 retailers as of October 31, 2026, with prices from £21,943 to £33,869, a £11,926 spread on the same certified stone. MOH London lists it at £33,869. 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.
