This 20.1ct 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 LG832604741 or 832604741. Listed at 11 retailers as of October 30, 2026, with prices from £4,624 to £20,718, a £16,094 spread on the same certified stone. Adiamor lists it at £20,718. 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.
