This 3.09ct lab-grown emerald sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840646235 or 840646235. Listed at 11 retailers as of October 27, 2026, with prices from £333 to £1,560, a £1,227 spread on the same certified stone. Brilliance lists it at £1,560. 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.
