About this 1.2ct lab-grown emerald diamond

This 1.2ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831693669 or 831693669. Listed at 8 retailers as of October 29, 2026, with prices from £248 to £1,727, a £1,479 spread on the same certified stone. Brilliant Earth lists it at £1,727. 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.
