About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG389919827 or 389919827. Listed at 11 retailers as of October 29, 2026, with prices from €126 to €504, a €378 spread on the same certified stone. NZ Jewellers lists it at €504. 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.
