About this 0.91ct lab-grown marquise diamond

This 0.91ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG823644547 or 823644547. Listed at 10 retailers as of October 29, 2026, with prices from €404 to €1,073, a €670 spread on the same certified stone. MOH London lists it at €1,073. 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.
