About this 1.5ct lab-grown emerald diamond

This 1.5ct 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 LG842630116 or 842630116. Listed at 14 retailers as of October 31, 2026, with prices from $158 to $1,040, a $882 spread on the same certified stone. Brilliant Earth lists it at $1,040. 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.
