About this 1.05ct lab-grown emerald diamond

This 1.05ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG840620554 or 840620554. Listed at 7 retailers as of November 4, 2026, with prices from $443 to $1,204, a $762 spread on the same certified stone. MOH London lists it at $1,204. 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.
