This 1.55ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG754501645 or 754501645. Listed at 8 retailers as of October 26, 2026, with prices from €150 to €872, a €722 spread on the same certified stone. MOH London lists it at €872. 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.
