About this 0.9ct lab-grown emerald diamond

This 0.9ct lab-grown emerald sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG496142450 or 496142450. Listed at 18 retailers as of October 29, 2026, with prices from $285 to $2,724, a $2,439 spread on the same certified stone. Do Amore Diamonds lists it at $2,724. 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.
