About this 5.21ct natural radiant diamond

This 5.21ct natural radiant sits in the over five carat band, graded I 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 1236164654. Listed at 10 retailers as of October 31, 2026, with prices from $78,538 to $106,486, a $27,948 spread on the same certified stone. Yorxs lists it at $106,486. 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.
