This 1.9ct 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 LG464107525 or 464107525. Listed at 13 retailers as of October 28, 2026, with prices from $265 to $1,943, a $1,678 spread on the same certified stone. Rare Carat lists it at $1,943. 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.
