About this 0.48ct lab-grown round diamond

This 0.48ct 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 LG816603143 or 816603143. Listed at 17 retailers as of October 29, 2026, with prices from £107 to £634, a £527 spread on the same certified stone. MOH London lists it at £634. 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.
