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 LG764652897 or 764652897. Listed at 21 retailers as of October 30, 2026, with prices from £186 to £1,007, a £821 spread on the same certified stone. Reve Diamonds lists it at £1,007. 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.
