About this 0.43ct lab-grown round diamond

This 0.43ct lab-grown round sits in the sub-half-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG791649772 or 791649772. Listed at 14 retailers as of November 2, 2026, with prices from £88 to £1,018, a £930 spread on the same certified stone. MOH London lists it at £1,018. 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.
