About this 1.64ct lab-grown emerald diamond

This 1.64ct 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 standard cut grade and certified by IGI LG541253245 or 541253245. Listed at 14 retailers as of October 30, 2026, with prices from €230 to €1,020, a €790 spread on the same certified stone. MOH London lists it at €1,020. 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.
