This 20.01ct lab-grown emerald sits in the over five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG846634033 or 846634033. Listed at 5 retailers as of October 31, 2026, with prices from €4,983 to €22,479, a €17,496 spread on the same certified stone. Adiamor lists it at €22,479. 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.
