This 1.78ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836603451 or 836603451. Listed at 12 retailers as of October 30, 2026, with prices from €768 to €4,135, a €3,368 spread on the same certified stone. Brilliant Earth lists it at €4,135. 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.
