About this 0.77ct lab-grown emerald diamond

This 0.77ct lab-grown emerald 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 LG621480438 or 621480438. Listed at 20 retailers as of October 29, 2026, with prices from £194 to £1,035, a £841 spread on the same certified stone. Reve Diamonds lists it at £1,035. 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.
