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 VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2231694235. Listed at 24 retailers as of October 29, 2026, with prices from $21,171 to $36,519, a $15,348 spread on the same certified stone. MOH London lists it at $36,519. 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.
