About this 0.79ct lab-grown marquise diamond

This 0.79ct 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 LG807610389 or 807610389. Listed at 21 retailers as of November 4, 2026, with prices from £344 to £1,977, a £1,633 spread on the same certified stone. Riddles Jewelry lists it at £1,977. 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.
