About this 1.09ct lab-grown emerald diamond

This 1.09ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG638477601 or 638477601. Listed at 33 retailers as of October 27, 2026, with prices from $246 to $2,434, a $2,188 spread on the same certified stone. Brilliant Earth lists it at $2,434. 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.
