About this 0.42ct natural radiant diamond

This 0.42ct natural radiant sits in the sub-half-carat band, graded D colour (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 6561203790. Listed at 9 retailers as of November 4, 2026, with prices from £828 to £1,427, a £598 spread on the same certified stone. Flawless Fine Jewelry lists it at £1,427. 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.
