About this 3.51ct natural marquise diamond

This 3.51ct 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 7546320553. Listed at 9 retailers as of November 2, 2026, with prices from $68,032 to $115,339, a $47,307 spread on the same certified stone. MOH London lists it at $115,339. 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.
