This 1.04ct lab-grown emerald sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG407932684 or 407932684. Listed at 4 retailers as of November 3, 2026, with prices from £364 to £3,019, a £2,655 spread on the same certified stone. MOH London lists it at £3,019. 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.
