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 VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 10 retailers as of October 28, 2026, with prices from $24,536 to $43,928, a $19,393 spread on the same certified stone. MOH London lists it at $43,928. 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.
