About this 0.83ct lab-grown oval diamond

This 0.83ct 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 LG818653988 or 818653988. Listed at 14 retailers as of October 29, 2026, with prices from £306 to £1,332, a £1,026 spread on the same certified stone. MOH London lists it at £1,332. 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.
