About this 0.4ct lab-grown emerald diamond
This 0.4ct lab-grown emerald sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG828618437 or 828618437. Listed at 18 retailers as of November 5, 2026, with prices from $178 to $1,015, a $837 spread on the same certified stone. MOH London lists it at $1,015. 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.
