About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5151437515. Listed at 4 retailers as of November 6, 2026, with a relatively tight 7% spread, which is unusual at this carat range and suggests competitive pricing across the listings. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
