This 1.03ct lab-grown emerald sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG407950698 or 407950698. Listed at 11 retailers as of October 29, 2026, with prices from $490 to $4,046, a $3,556 spread on the same certified stone. MOH London lists it at $4,046. 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.
