This 2.51ct lab-grown emerald sits in the two to three carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816610560 or 816610560. Listed at 21 retailers as of October 31, 2026, with prices from $1,389 to $7,370, a $5,981 spread on the same certified stone. Brilliant Earth lists it at $7,370. 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.
