About this 0.86ct lab-grown marquise diamond

This 0.86ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG828681322 or 828681322. Listed at 19 retailers as of November 4, 2026, with prices from £178 to £979, a £802 spread on the same certified stone. Reve Diamonds lists it at £979. 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.
