About this 0.43ct lab-grown marquise diamond

This 0.43ct 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 LG805678356 or 805678356. Listed at 21 retailers as of October 29, 2026, with prices from €178 to €1,037, a €859 spread on the same certified stone. MOH London lists it at €1,037. 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.
