About this 0.97ct lab-grown oval diamond

This 0.97ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG799646923 or 799646923. Listed at 20 retailers as of October 29, 2026, with prices from £137 to £984, a £846 spread on the same certified stone. Brilliant Earth lists it at £984. 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.
