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 17 retailers as of October 29, 2026, with prices from $228 to $1,307, a $1,079 spread on the same certified stone. MOH London lists it at $1,307. 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.
