About this 1.05ct natural cushion diamond

This 1.05ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2171395305. Listed at 2 retailers as of November 4, 2026, with a relatively tight 9% 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.
