This 1.53ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG492126911 or 492126911. Listed at 4 retailers as of October 29, 2026, with prices from £346 to £816, a £470 spread on the same certified stone. MOH London lists it at £816. 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.
