About this 0.78ct lab-grown oval diamond

This 0.78ct 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 LG809650766 or 809650766. Listed at 20 retailers as of October 29, 2026, with prices from £145 to £876, a £731 spread on the same certified stone. Reve Diamonds lists it at £876. 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.
