About this 0.83ct lab-grown marquise diamond

This 0.83ct 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 LG808614322 or 808614322. Listed at 21 retailers as of November 3, 2026, with prices from £184 to £939, a £754 spread on the same certified stone. Reve Diamonds lists it at £939. 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.
