About this 0.39ct lab-grown round diamond

This 0.39ct lab-grown round 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 LG690524536 or 690524536. Listed at 14 retailers as of October 31, 2026, with prices from £90 to £486, a £396 spread on the same certified stone. Taylor and Hart lists it at £486. 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.
