About this 0.43ct lab-grown emerald diamond

This 0.43ct 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 LG814631456 or 814631456. Listed at 19 retailers as of October 26, 2026, with prices from $173 to $1,003, a $830 spread on the same certified stone. MOH London lists it at $1,003. 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.
