About this 4.01ct natural radiant diamond

This 4.01ct natural radiant sits in the three to five carat band, graded J 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 5231279399. Listed at 9 retailers as of November 6, 2026, with prices from £34,963 to £43,610, a £8,648 spread on the same certified stone. 77 Diamonds lists it at £43,610. 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.
