About this 0.42ct lab-grown marquise diamond

This 0.42ct lab-grown marquise sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG838608699 or 838608699. Listed at 19 retailers as of November 2, 2026, with prices from $332 to $1,923, a $1,591 spread on the same certified stone. MOH London lists it at $1,923. 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.
