This 20.08ct lab-grown emerald sits in the over five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831691591 or 831691591. Listed at 5 retailers as of October 30, 2026, with prices from £4,281 to £20,281, a £16,000 spread on the same certified stone. Adiamor lists it at £20,281. 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.
