About this 0.86ct lab-grown oval diamond

This 0.86ct 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 LG811638609 or 811638609. Listed at 18 retailers as of October 29, 2026, with prices from £238 to £1,189, a £951 spread on the same certified stone. MOH London lists it at £1,189. 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.
