About this 15.21ct natural oval diamond

This 15.21ct natural oval sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5222985378. Listed at 2 retailers as of November 2, 2026, with a relatively tight 11% 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.
