About this 2.51ct natural heart diamond

This 2.51ct natural heart sits in the two to three carat band, graded I colour (near-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 1548247521. Listed at 16 retailers as of October 29, 2026, with prices from £10,627 to £18,995, a £8,368 spread on the same certified stone. MOH London lists it at £18,995. 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.
