About this 0.57ct lab-grown emerald diamond

This 0.57ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG818670770 or 818670770. Listed at 20 retailers as of October 30, 2026, with prices from $316 to $1,460, a $1,144 spread on the same certified stone. Reve Diamonds lists it at $1,460. 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.
