About this 0.77ct lab-grown round diamond

This 0.77ct lab-grown round 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 LG842605993 or 842605993. Listed at 8 retailers as of October 28, 2026, with prices from £197 to £679, a £481 spread on the same certified stone. MOH London lists it at £679. 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.
