About this 2.25ct natural round diamond

This 2.25ct natural round sits in the two to three carat band, graded K colour (faint-tinted) and I1 clarity (included), with a top-tier cut grade and certified by GIA 2557372951. Listed at 8 retailers as of November 4, 2026, with a 35% 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.
