This 1.02ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407998497 or 407998497. Listed at 9 retailers as of October 26, 2026, with prices from $610 to $3,473, a $2,863 spread on the same certified stone. MOH London lists it at $3,473. 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.
