About this 1.23ct lab-grown emerald diamond

This 1.23ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634386 or 840634386. Listed at 13 retailers as of November 4, 2026, with prices from €257 to €1,926, a €1,669 spread on the same certified stone. Brilliant Earth lists it at €1,926. 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.
