About this 1.7ct lab-grown emerald diamond

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 28, 2026, with prices from $447 to $2,982, a $2,535 spread on the same certified stone. Rare Carat lists it at $2,982. 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.
