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 LG812621282 or 812621282. Listed at 20 retailers as of October 28, 2026, with prices from €330 to €1,435, a €1,106 spread on the same certified stone. Brilliant Earth lists it at €1,435. 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.
