About this 0.98ct lab-grown oval diamond

This 0.98ct 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 LG799619464 or 799619464. Listed at 33 retailers as of October 29, 2026, with prices from £138 to £978, a £840 spread on the same certified stone. Brilliant Earth lists it at £978. 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.
