About this 0.99ct lab-grown oval diamond

This 0.99ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG840608824 or 840608824. Listed at 20 retailers as of October 28, 2026, with prices from £237 to £1,149, a £912 spread on the same certified stone. Reve Diamonds lists it at £1,149. 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.
