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 LG800675086 or 800675086. Listed at 8 retailers as of October 29, 2026, with prices from $448 to $1,501, a $1,052 spread on the same certified stone. MOH London lists it at $1,501. 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.
