This 1.71ct 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 LG508141059 or 508141059. Listed at 15 retailers as of October 30, 2026, with prices from €173 to €1,226, a €1,054 spread on the same certified stone. Brilliant Earth lists it at €1,226. 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.
