About this 2.51ct lab-grown emerald diamond

This 2.51ct 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 LG846640240 or 846640240. Listed at 13 retailers as of October 30, 2026, with prices from $1,576 to $10,007, a $8,431 spread on the same certified stone. Brilliant Earth lists it at $10,007. 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.
