About this 1.2ct lab-grown emerald diamond

This 1.2ct 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 LG831684517 or 831684517. Listed at 7 retailers as of October 30, 2026, with prices from $330 to $2,870, a $2,540 spread on the same certified stone. Brilliant Earth lists it at $2,870. 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.
