About this 0.81ct lab-grown marquise diamond

This 0.81ct 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 LG805647144 or 805647144. Listed at 25 retailers as of November 4, 2026, with prices from $366 to $1,959, a $1,593 spread on the same certified stone. Reve Diamonds lists it at $1,959. 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.
