About this 2.66ct lab-grown emerald diamond

This 2.66ct lab-grown emerald sits in the two to three carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG840617175 or 840617175. Listed at 10 retailers as of November 1, 2026, with prices from $1,630 to $5,375, a $3,745 spread on the same certified stone. Rare Carat lists it at $5,375. 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.
