About this 1.23ct lab-grown emerald diamond

This 1.23ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1509037105. Listed at 3 retailers as of October 28, 2026, with prices from €474 to €1,620, a €1,146 spread on the same certified stone. Do Amore Diamonds lists it at €1,620. 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.
