This 1.52ct 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 standard cut grade and certified by IGI LG668408830 or 668408830. Listed at 14 retailers as of October 27, 2026, with prices from £134 to £1,081, a £947 spread on the same certified stone. Brilliant Earth lists it at £1,081. 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.
