About this 0.4ct lab-grown marquise diamond

This 0.4ct 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 LG768616865 or 768616865. Listed at 22 retailers as of October 26, 2026, with prices from €170 to €932, a €762 spread on the same certified stone. MOH London lists it at €932. 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.
