About this 2.09ct lab-grown emerald diamond

This 2.09ct lab-grown emerald sits in the two to three carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG506192426 or 506192426. Listed at 14 retailers as of October 27, 2026, with prices from £199 to £1,720, a £1,521 spread on the same certified stone. Brilliant Earth lists it at £1,720. 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.
