This 1.76ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG780640462 or 780640462. Listed at 10 retailers as of October 28, 2026, with prices from $522 to $2,610, a $2,088 spread on the same certified stone. Rare Carat lists it at $2,610. 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.
