About this 4.51ct natural radiant diamond

This 4.51ct natural radiant sits in the three to five carat band, graded E colour (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. Listed at 3 retailers as of October 29, 2026, with prices from $179,237 to $230,539, a $51,302 spread on the same certified stone. GS Diamonds lists it at $230,539. 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.
