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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818635240 or 818635240. Listed at 22 retailers as of October 31, 2026, with prices from €442 to €2,549, a €2,107 spread on the same certified stone. Riddles Jewelry lists it at €2,549. 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.
