About this 3.06ct natural radiant diamond

This 3.06ct natural radiant sits in the three to five carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), 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 5, 2026, with prices from £26,360 to £30,623, a £4,263 spread on the same certified stone. Blue Nile lists it at £30,623. 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.
