About this 3.51ct natural marquise diamond

This 3.51ct natural marquise sits in the three to five carat band, graded D colour (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 1545100378. Listed at 11 retailers as of October 29, 2026, with prices from $106,313 to $174,568, a $68,255 spread on the same certified stone. MOH London lists it at $174,568. 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.
