About this 5.12ct natural radiant diamond

This 5.12ct natural radiant sits in the over five carat band, graded J 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 15226320. Listed at 17 retailers as of October 30, 2026, with prices from €50,367 to €86,800, a €36,433 spread on the same certified stone. MOH London lists it at €86,800. 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.
