About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded H 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 7563643321. Listed at 10 retailers as of October 30, 2026, with prices from £15,008 to £19,706, a £4,698 spread on the same certified stone. Taylor and Hart lists it at £19,706. 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.
