About this 1.03ct lab-grown emerald diamond

This 1.03ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG787613127 or 787613127. Listed at 22 retailers as of October 27, 2026, with prices from £131 to £1,262, a £1,130 spread on the same certified stone. Do Amore Diamonds lists it at £1,262. 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.
