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 LG731580553 or 731580553. Listed at 23 retailers as of October 29, 2026, with prices from £122 to £1,761, a £1,640 spread on the same certified stone. Do Amore Diamonds lists it at £1,761. 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.
