About this 0.86ct lab-grown marquise diamond

This 0.86ct 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 LG821694685 or 821694685. Listed at 9 retailers as of November 1, 2026, with prices from $422 to $1,234, a $812 spread on the same certified stone. MOH London lists it at $1,234. 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.
