About this 3.53ct natural marquise diamond

This 3.53ct natural marquise sits in the three to five carat band, graded I 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 3 retailers as of November 4, 2026, with prices from £36,020 to £41,516, a £5,496 spread on the same certified stone. Blue Nile lists it at £41,516. 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.
