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 8 retailers as of October 31, 2026, with prices from $470 to $4,086, a $3,616 spread on the same certified stone. Brilliant Earth lists it at $4,086. 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.
