About this 0.41ct lab-grown marquise diamond

This 0.41ct 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 LG800638210 or 800638210. Listed at 20 retailers as of October 30, 2026, with prices from $267 to $1,545, a $1,278 spread on the same certified stone. MOH London lists it at $1,545. 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.
