About this 0.31ct natural marquise diamond

This 0.31ct natural marquise sits in the sub-half-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6565450628. Listed at 11 retailers as of November 2, 2026, with a 86% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
