About this 0.34ct lab-grown marquise diamond

This 0.34ct 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 LG669454733 or 669454733. Listed at 18 retailers as of October 30, 2026, with prices from £106 to £751, a £645 spread on the same certified stone. Flawless Fine Jewelry lists it at £751. 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.
