About this 1.07ct lab-grown emerald diamond

This 1.07ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI LG804618206 or 804618206. Listed at 15 retailers as of October 30, 2026, with a relatively tight 20% spread, which is unusual at this carat range and suggests competitive pricing across the listings. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
