About this 0.65ct lab-grown marquise diamond

This 0.65ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG821659891 or 821659891. Listed at 19 retailers as of November 4, 2026, with prices from €337 to €1,910, a €1,573 spread on the same certified stone. Riddles Jewelry lists it at €1,910. 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.
