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 FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG811641402 or 811641402. Listed at 20 retailers as of October 30, 2026, with prices from €182 to €1,017, a €835 spread on the same certified stone. Reve Diamonds lists it at €1,017. 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.
