About this 0.78ct lab-grown emerald diamond

This 0.78ct lab-grown emerald 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 LG848698422 or 848698422. Listed at 12 retailers as of November 4, 2026, with prices from £185 to £777, a £592 spread on the same certified stone. Taylor and Hart lists it at £777. 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.
