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 6492573712. Listed at 21 retailers as of October 30, 2026, with prices from £14,853 to £25,234, a £10,381 spread on the same certified stone. MOH London lists it at £25,234. 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.
