About this 0.91ct lab-grown marquise diamond

This 0.91ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG724530688 or 724530688. Listed at 22 retailers as of October 30, 2026, with prices from £199 to £1,049, a £850 spread on the same certified stone. Reve Diamonds lists it at £1,049. 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.
