About this 1.55ct lab-grown emerald diamond

This 1.55ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG847678919 or 847678919. Listed at 3 retailers as of October 31, 2026, with prices from €346 to €675, a €329 spread on the same certified stone. Taylor and Hart lists it at €675. 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.
