About this 0.8ct natural heart diamond

This 0.8ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and I1 clarity (included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2426125759. Listed at 9 retailers as of November 1, 2026, with a 52% 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.
