About this 0.8ct lab-grown marquise diamond

This 0.8ct 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 LG799608344 or 799608344. Listed at 10 retailers as of November 2, 2026, with prices from €822 to €2,434, a €1,612 spread on the same certified stone. Do Amore Diamonds lists it at €2,434. 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.
