About this 0.54ct natural marquise diamond

This 0.54ct natural marquise sits in the half to three-quarter carat band, graded H 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 6551820355. Listed at 21 retailers as of November 3, 2026, with prices from $968 to $3,902, a $2,934 spread on the same certified stone. NZ Jewellers lists it at $3,902. 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.
