About this 0.82ct lab-grown marquise diamond

This 0.82ct 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 LG807610385 or 807610385. Listed at 22 retailers as of November 4, 2026, with prices from £334 to £1,912, a £1,578 spread on the same certified stone. Riddles Jewelry lists it at £1,912. 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.
