About this 2.51ct natural marquise diamond

This 2.51ct natural marquise 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 1558951189. Listed at 10 retailers as of November 1, 2026, with prices from $21,773 to $39,390, a $17,618 spread on the same certified stone. MOH London lists it at $39,390. 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.
