About this 1.2ct natural oval diamond

This 1.2ct natural oval sits in the classic one-carat band, graded M 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 6511678413. Listed at 10 retailers as of November 5, 2026, with a relatively tight 13% 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.
