About this 0.5ct lab-grown emerald diamond

This 0.5ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG790638883 or 790638883. Listed at 11 retailers as of October 26, 2026, with prices from £244 to £658, a £414 spread on the same certified stone. MOH London lists it at £658. 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.
