About this 0.56ct lab-grown marquise diamond

This 0.56ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817618402 or 817618402. Listed at 6 retailers as of November 1, 2026, with prices from $331 to $831, a $500 spread on the same certified stone. MOH London lists it at $831. 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.
