This 1.28ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG595392716 or 595392716. Listed at 14 retailers as of October 30, 2026, with prices from £149 to £1,276, a £1,128 spread on the same certified stone. Do Amore Diamonds lists it at £1,276. 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.
