About this 0.53ct natural marquise diamond

This 0.53ct 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 6551574276. Listed at 5 retailers as of November 4, 2026, with a relatively tight 12% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
