About this 0.74ct lab-grown marquise diamond

This 0.74ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG821694682 or 821694682. Listed at 9 retailers as of November 1, 2026, with prices from £274 to £801, a £527 spread on the same certified stone. MOH London lists it at £801. 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.
