This 1.78ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG636411139 or 636411139. Listed at 3 retailers as of October 26, 2026, with prices from $1,270 to $1,830, a $560 spread on the same certified stone. Kay Jewelers lists it at $1,830. 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.
