About this 0.46ct lab-grown marquise diamond

This 0.46ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG807610158 or 807610158. Listed at 18 retailers as of November 3, 2026, with prices from £204 to £1,180, a £976 spread on the same certified stone. MOH London lists it at £1,180. 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.
