About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded H colour (near-colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by HRD 260000125771. Listed at 10 retailers as of October 30, 2026, with prices from $8,643 to $18,194, a $9,552 spread on the same certified stone. NZ Jewellers lists it at $18,194. 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.
