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 LG831689643 or 831689643. Listed at 3 retailers as of October 31, 2026, with prices from £5,274 to £20,281, a £15,007 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.
