This 1.61ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG502109446 or 502109446. Listed at 13 retailers as of October 28, 2026, with prices from £218 to £1,367, a £1,149 spread on the same certified stone. Brilliant Earth lists it at £1,367. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
