About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG602380874 or 602380874. Listed at 22 retailers as of October 28, 2026, with prices from £147 to £1,217, a £1,069 spread on the same certified stone. Brilliant Earth lists it at £1,217. 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.
