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 very-good cut grade and certified by IGI LG615357492 or 615357492. Listed at 20 retailers as of October 27, 2026, with prices from £128 to £1,171, a £1,044 spread on the same certified stone. Brilliant Earth lists it at £1,171. 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.
