About this 0.83ct lab-grown marquise diamond

This 0.83ct 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 LG815641237 or 815641237. Listed at 6 retailers as of November 1, 2026, with prices from €400 to €1,691, a €1,290 spread on the same certified stone. MOH London lists it at €1,691. 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.
