About this 1.21ct lab-grown heart diamond

This 1.21ct lab-grown heart sits in the classic one-carat band, graded F colour (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 6531104567. Listed at 18 retailers as of November 4, 2026, with a 379% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
