This 1.7ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG678534405 or 678534405. Listed at 19 retailers as of October 27, 2026, with prices from $251 to $1,675, a $1,424 spread on the same certified stone. Rare Carat lists it at $1,675. 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.
