About this 0.4ct natural radiant diamond

This 0.4ct natural radiant sits in the sub-half-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 797679497. Listed at 9 retailers as of October 30, 2026, with prices from £231 to £1,246, a £1,015 spread on the same certified stone. NZ Jewellers lists it at £1,246. 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.
