About this 0.4ct natural radiant diamond

This 0.4ct natural radiant sits in the sub-half-carat band, graded E 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 7566536591. Listed at 8 retailers as of October 29, 2026, with prices from £732 to £1,213, a £481 spread on the same certified stone. Flawless Fine Jewelry lists it at £1,213. 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.
