About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade and certified by GIA 6532025212. Listed at 14 retailers as of October 25, 2026, with a 118% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
