About this 0.81ct lab-grown oval diamond

This 0.81ct lab-grown oval 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 LG818671768 or 818671768. Listed at 22 retailers as of November 1, 2026, with prices from £251 to £1,132, a £881 spread on the same certified stone. Reve Diamonds lists it at £1,132. 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.
