About this 0.77ct lab-grown marquise diamond

This 0.77ct 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 LG790611930 or 790611930. Listed at 22 retailers as of November 4, 2026, with prices from $309 to $1,779, a $1,469 spread on the same certified stone. Reve Diamonds lists it at $1,779. 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.
