This 1.78ct lab-grown emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG600370054 or 600370054. Listed at 11 retailers as of October 29, 2026, with prices from £346 to £1,637, a £1,291 spread on the same certified stone. Do Amore Diamonds lists it at £1,637. 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.
