About this 0.41ct lab-grown marquise diamond

This 0.41ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG807610414 or 807610414. Listed at 17 retailers as of October 29, 2026, with prices from £162 to £797, a £635 spread on the same certified stone. MOH London lists it at £797. 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.
