About this 0.31ct lab-grown emerald diamond

This 0.31ct lab-grown emerald sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG808635378 or 808635378. Listed at 15 retailers as of October 28, 2026, with prices from £116 to £585, a £469 spread on the same certified stone. Taylor and Hart lists it at £585. 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.
