About this 0.85ct lab-grown marquise diamond

This 0.85ct 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 LG812621720 or 812621720. Listed at 20 retailers as of November 1, 2026, with prices from $363 to $1,814, a $1,451 spread on the same certified stone. Reve Diamonds lists it at $1,814. 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.
