About this 2.51ct natural princess diamond

This 2.51ct natural princess sits in the two to three carat band, graded I colour (near-colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5221816201. Listed at 8 retailers as of October 30, 2026, with prices from $19,886 to $30,646, a $10,760 spread on the same certified stone. NZ Jewellers lists it at $30,646. 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.
