About this 0.45ct lab-grown marquise diamond

This 0.45ct 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 LG807610160 or 807610160. Listed at 14 retailers as of November 5, 2026, with prices from £201 to £1,154, a £953 spread on the same certified stone. MOH London lists it at £1,154. 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.
