About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded D colour (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 6512438251. Listed at 7 retailers as of October 30, 2026, with prices from $45,870 to $57,913, a $12,043 spread on the same certified stone. 77 Diamonds lists it at $57,913. 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.
