About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three carat band, graded J 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 2558740522. Listed at 22 retailers as of November 4, 2026, with prices from $29,492 to $51,473, a $21,981 spread on the same certified stone. MOH London lists it at $51,473. 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.
