About this 0.9ct lab-grown marquise diamond

This 0.9ct 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 LG804625039 or 804625039. Listed at 22 retailers as of October 31, 2026, with prices from $696 to $4,010, a $3,314 spread on the same certified stone. Riddles Jewelry lists it at $4,010. 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.
