This 1.59ct 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 LG680572076 or 680572076. Listed at 8 retailers as of October 27, 2026, with prices from £138 to £695, a £557 spread on the same certified stone. MOH London lists it at £695. 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.
