About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2557478886. Listed at 20 retailers as of November 4, 2026, with a 137% 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.
