This 3.99ct lab-grown emerald sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG797602104 or 797602104. Listed at 6 retailers as of October 26, 2026, with prices from £630 to £4,453, a £3,823 spread on the same certified stone. Brilliant Earth lists it at £4,453. 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.
