About this 20.45ct natural radiant diamond

This 20.45ct natural radiant sits in the over five carat band, graded H 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 2175718425. Listed at 5 retailers as of October 31, 2026, with prices from €831,219 to €1,125,032, a €293,814 spread on the same certified stone. Yorxs lists it at €1,125,032. 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.
