This 1.59ct 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 LG847679091 or 847679091. Listed at 3 retailers as of November 1, 2026, with prices from $621 to $1,650, a $1,029 spread on the same certified stone. MOH London lists it at $1,650. 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.
