About this 0.33ct lab-grown marquise diamond

This 0.33ct lab-grown marquise 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 LG837641453 or 837641453. Listed at 17 retailers as of October 26, 2026, with prices from £107 to £618, a £511 spread on the same certified stone. MOH London lists it at £618. 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.
