About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three 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 2564718954. Listed at 8 retailers as of October 30, 2026, with prices from $25,638 to $40,822, a $15,183 spread on the same certified stone. NZ Jewellers lists it at $40,822. 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.
