About this 0.74ct lab-grown marquise diamond

This 0.74ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818662730 or 818662730. Listed at 20 retailers as of October 29, 2026, with prices from $487 to $1,994, a $1,507 spread on the same certified stone. MOH London lists it at $1,994. 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.
