About this 0.41ct lab-grown round diamond

This 0.41ct lab-grown round sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG728504545 or 728504545. Listed at 13 retailers as of October 29, 2026, with prices from £116 to £672, a £557 spread on the same certified stone. MOH London lists it at £672. 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.
