About this 0.42ct lab-grown emerald diamond

This 0.42ct lab-grown emerald sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG816634840 or 816634840. Listed at 19 retailers as of October 29, 2026, with prices from $300 to $1,753, a $1,453 spread on the same certified stone. MOH London lists it at $1,753. 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.
