About this 0.34ct lab-grown marquise diamond

This 0.34ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG784631395 or 784631395. Listed at 16 retailers as of October 26, 2026, with prices from $142 to $908, a $766 spread on the same certified stone. MOH London lists it at $908. 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.
