This 1.45ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG551277266 or 551277266. Listed at 10 retailers as of October 30, 2026, with prices from €197 to €1,307, a €1,110 spread on the same certified stone. Brilliant Earth lists it at €1,307. 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.
