About this 1.23ct natural heart diamond

This 1.23ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 7542121029. Listed at 16 retailers as of November 4, 2026, with a 119% 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.
