This 1.01ct 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 LG407935462 or 407935462. Listed at 11 retailers as of November 4, 2026, with prices from £357 to £2,926, a £2,569 spread on the same certified stone. MOH London lists it at £2,926. 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.
