This 1.31ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG621489080 or 621489080. Listed at 13 retailers as of October 30, 2026, with prices from £147 to £1,261, a £1,114 spread on the same certified stone. Do Amore Diamonds lists it at £1,261. 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.
