About this 0.66ct natural marquise diamond

This 0.66ct 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 6565518237. Listed at 14 retailers as of October 30, 2026, with prices from £572 to £1,888, a £1,315 spread on the same certified stone. NZ Jewellers lists it at £1,888. 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.
