About this 0.55ct lab-grown emerald diamond

This 0.55ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818670768 or 818670768. Listed at 20 retailers as of October 30, 2026, with prices from £229 to £1,069, a £839 spread on the same certified stone. Reve Diamonds lists it at £1,069. 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.
