About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded I 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 1548941158. Listed at 8 retailers as of October 27, 2026, with prices from $17,379 to $21,749, a $4,370 spread on the same certified stone. Yorxs lists it at $21,749. 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.
