About this 0.51ct lab-grown emerald diamond

This 0.51ct lab-grown emerald sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG670422659 or 670422659. Listed at 24 retailers as of October 24, 2026, with prices from $224 to $1,392, a $1,168 spread on the same certified stone. Reve Diamonds lists it at $1,392. 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.
