About this 0.4ct lab-grown emerald diamond

This 0.4ct 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 LG822610790 or 822610790. Listed at 16 retailers as of October 29, 2026, with prices from $185 to $1,064, a $879 spread on the same certified stone. MOH London lists it at $1,064. 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.
