About this 0.45ct lab-grown marquise diamond

This 0.45ct 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 LG843682804 or 843682804. Listed at 14 retailers as of November 1, 2026, with prices from $242 to $1,027, a $785 spread on the same certified stone. MOH London lists it at $1,027. 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.
