About this 1.21ct natural oval diamond

This 1.21ct natural oval sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6545391379. Listed at 9 retailers as of November 5, 2026, with a relatively tight 5% 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.
