This 1.57ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG530201667 or 530201667. Listed at 13 retailers as of October 29, 2026, with prices from $423 to $2,377, a $1,955 spread on the same certified stone. Brilliant Earth lists it at $2,377. 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.
