About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded H colour (near-colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 100773998422. Listed at a single retailer as of October 30, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
