About this 0.34ct lab-grown radiant diamond

This 0.34ct lab-grown radiant sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG675501680 or 675501680. Listed at 18 retailers as of October 30, 2026, with prices from £107 to £688, a £581 spread on the same certified stone. MOH London lists it at £688. 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.
