About this 0.4ct lab-grown marquise diamond

This 0.4ct 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 LG836623727 or 836623727. Listed at 20 retailers as of November 2, 2026, with prices from $332 to $1,925, a $1,593 spread on the same certified stone. MOH London lists it at $1,925. 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.
