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 standard cut grade and certified by IGI LG719544215 or 719544215. Listed at 2 retailers as of October 29, 2026, with prices from £834 to £4,463, a £3,629 spread on the same certified stone. Brilliant Earth lists it at £4,463. 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.
