About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade and certified by GIA 5242066430. Listed at 14 retailers as of November 4, 2026, with a 71% 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.
