This 0.8ct lab-grown emerald sits in the just-under-one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG384944704 or 384944704. Listed at 9 retailers as of October 29, 2026, with prices from £310 to £1,417, a £1,107 spread on the same certified stone. MOH London lists it at £1,417. 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.
