About this 0.78ct lab-grown asscher diamond

This 0.78ct lab-grown asscher 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 LG804673977 or 804673977. Listed at 23 retailers as of October 28, 2026, with prices from £156 to £944, a £788 spread on the same certified stone. Reve Diamonds lists it at £944. 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.
