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 €226 to €1,505, a €1,279 spread on the same certified stone. Rare Carat lists it at €1,505. 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.
