About this 1.22ct lab-grown heart diamond

This 1.22ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 1525951134. Listed at 21 retailers as of October 30, 2026, with a 372% 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.
