About this 1.05ct natural heart diamond

This 1.05ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) 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 6545820586. Listed at 3 retailers as of October 31, 2026, with a relatively tight 11% 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.
