This 1.5ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG560246399 or 560246399. Listed at 15 retailers as of November 4, 2026, with prices from $359 to $3,469, a $3,110 spread on the same certified stone. Brilliant Earth lists it at $3,469. 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.
