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 LG826695389 or 826695389. Listed at 19 retailers as of October 29, 2026, with prices from $289 to $1,442, a $1,153 spread on the same certified stone. MOH London lists it at $1,442. 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.
