About this 3.51ct natural radiant diamond

This 3.51ct natural radiant sits in the three to five carat band, graded I 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 1236974012. Listed at 5 retailers as of October 31, 2026, with prices from £27,654 to £35,020, a £7,366 spread on the same certified stone. 77 Diamonds lists it at £35,020. 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.
