About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded H 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 6555645341. Listed at 2 retailers as of October 31, 2026, with a relatively tight 3% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
