About this 0.5ct lab-grown emerald diamond

This 0.5ct lab-grown emerald sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG763635259 or 763635259. Listed at 17 retailers as of October 28, 2026, with prices from £145 to £879, a £734 spread on the same certified stone. Reve Diamonds lists it at £879. 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.
