About this 2.57ct lab-grown emerald diamond

This 2.57ct lab-grown emerald sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG644440123 or 644440123. Listed at 4 retailers as of October 30, 2026, with prices from $2,306 to $11,090, a $8,784 spread on the same certified stone. Kay Jewelers lists it at $11,090. 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.
