About this 1.02ct lab-grown emerald diamond

This 1.02ct 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 LG414063280 or 414063280. Listed at 11 retailers as of November 4, 2026, with prices from £364 to £2,953, a £2,589 spread on the same certified stone. MOH London lists it at £2,953. 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.
