About this 0.91ct lab-grown emerald diamond

This 0.91ct 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 LG606359125 or 606359125. Listed at 20 retailers as of October 29, 2026, with prices from £164 to £969, a £804 spread on the same certified stone. Brilliant Earth lists it at £969. 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.
