About this 0.92ct lab-grown marquise diamond

This 0.92ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817625562 or 817625562. Listed at 25 retailers as of October 27, 2026, with prices from £219 to £1,164, a £945 spread on the same certified stone. Brilliant Earth lists it at £1,164. 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.
