This 1.21ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG780695300 or 780695300. Listed at 9 retailers as of October 29, 2026, with prices from £130 to £1,247, a £1,117 spread on the same certified stone. Do Amore Diamonds lists it at £1,247. 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.
