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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG834615758 or 834615758. Listed at 12 retailers as of October 29, 2026, with prices from €217 to €1,260, a €1,043 spread on the same certified stone. MOH London lists it at €1,260. 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.
