About this 0.63ct natural marquise diamond

This 0.63ct natural marquise sits in the half to three-quarter 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 2558427069. Listed at 6 retailers as of October 31, 2026, with prices from £639 to £992, a £353 spread on the same certified stone. GemTrove lists it at £992. 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.
