About this 0.42ct lab-grown emerald diamond

This 0.42ct 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 LG825686719 or 825686719. Listed at 17 retailers as of October 28, 2026, with prices from $275 to $1,580, a $1,305 spread on the same certified stone. MOH London lists it at $1,580. 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.
