About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded H 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 2556451205. Listed at 5 retailers as of November 3, 2026, with prices from £23,158 to £28,524, a £5,366 spread on the same certified stone. Yorxs lists it at £28,524. 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.
