This 1.78ct lab-grown emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG600370054 or 600370054. Listed at 11 retailers as of October 29, 2026, with prices from $818 to $3,868, a $3,050 spread on the same certified stone. Do Amore Diamonds lists it at $3,868. 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.
