This 1.65ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG615387567 or 615387567. Listed at 5 retailers as of October 29, 2026, with prices from £345 to £894, a £549 spread on the same certified stone. MOH London lists it at £894. 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.
