About this 1.8ct lab-grown emerald diamond

This 1.8ct 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 very-good cut grade and certified by IGI LG566394899 or 566394899. Listed at 14 retailers as of October 31, 2026, with prices from $530 to $3,921, a $3,391 spread on the same certified stone. Do Amore Diamonds lists it at $3,921. 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.
