About this 0.77ct lab-grown asscher diamond

This 0.77ct lab-grown asscher sits in the just-under-one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG680504135 or 680504135. Listed at 10 retailers as of November 4, 2026, with prices from £325 to £875, a £550 spread on the same certified stone. MOH London lists it at £875. 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.
