This 20.1ct lab-grown emerald sits in the over five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG821674718 or 821674718. Listed at 9 retailers as of October 26, 2026, with prices from $10,173 to $34,818, a $24,645 spread on the same certified stone. Adiamor lists it at $34,818. 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.
