About this 0.9ct lab-grown emerald diamond

This 0.9ct 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 LG657420595 or 657420595. Listed at 25 retailers as of October 23, 2026, with prices from £117 to £1,221, a £1,104 spread on the same certified stone. Queensmith lists it at £1,221. 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.
