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 27, 2026, with prices from $275 to $1,950, a $1,675 spread on the same certified stone. Brilliant Earth lists it at $1,950. 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.
