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 1563055961. Listed at 13 retailers as of October 29, 2026, with prices from £11,474 to £21,970, a £10,496 spread on the same certified stone. With Clarity lists it at £21,970. 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.
