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 LG683509074 or 683509074. Listed at 25 retailers as of October 29, 2026, with prices from $214 to $2,050, a $1,836 spread on the same certified stone. Do Amore Diamonds lists it at $2,050. 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.
