About this 25.17ct natural oval diamond

This 25.17ct natural oval sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2235974356. Listed at 5 retailers as of October 29, 2026, with prices from £1,364,716 to £1,746,612, a £381,896 spread on the same certified stone. Fonder Diamond lists it at £1,746,612. 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.
