About this 12.53ct natural radiant diamond

This 12.53ct natural radiant sits in the over five carat band, graded FANCY YELLOW colour (tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2241040507. Listed at 7 retailers as of November 2, 2026, with prices from $377,783 to $509,819, a $132,037 spread on the same certified stone. William & Sons Jewelers lists it at $509,819. 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.
