About this 1.09ct lab-grown emerald diamond

This 1.09ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG698508863 or 698508863. Listed at 14 retailers as of November 1, 2026, with prices from £99 to £1,026, a £927 spread on the same certified stone. MOH London lists it at £1,026. 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.
