About this 0.5ct natural marquise diamond

This 0.5ct 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 6561463613. Listed at 13 retailers as of October 31, 2026, with prices from £536 to £1,126, a £590 spread on the same certified stone. Flawless Fine Jewelry lists it at £1,126. 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.
