About this 0.37ct lab-grown marquise diamond

This 0.37ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG836674413 or 836674413. Listed at 16 retailers as of November 1, 2026, with prices from $222 to $1,222, a $1,000 spread on the same certified stone. MOH London lists it at $1,222. 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.
