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 IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG823695084 or 823695084. Listed at 20 retailers as of October 30, 2026, with prices from $389 to $2,033, a $1,644 spread on the same certified stone. Brilliant Earth lists it at $2,033. 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.
