This 1.37ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG756567269 or 756567269. Listed at 9 retailers as of October 25, 2026, with prices from £117 to £681, a £564 spread on the same certified stone. MOH London lists it at £681. 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.
