About this 0.54ct lab-grown emerald diamond

This 0.54ct 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 LG803644278 or 803644278. Listed at 20 retailers as of October 29, 2026, with prices from £108 to £731, a £622 spread on the same certified stone. Michael Trio lists it at £731. 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.
