About this 1.04ct lab-grown emerald diamond

This 1.04ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831690487 or 831690487. Listed at 9 retailers as of October 30, 2026, with prices from £181 to £1,455, a £1,275 spread on the same certified stone. Brilliant Earth lists it at £1,455. 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.
