About this 1.01ct lab-grown emerald diamond

This 1.01ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407972863 or 407972863. Listed at 11 retailers as of November 3, 2026, with prices from $754 to $4,584, a $3,831 spread on the same certified stone. MOH London lists it at $4,584. 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.
