About this 1.23ct natural marquise diamond

This 1.23ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6551735070. Listed at 16 retailers as of November 2, 2026, with a 73% 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.
