This 0.5ct lab-grown emerald sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407941546 or 407941546. Listed at 11 retailers as of October 29, 2026, with prices from $239 to $1,196, a $957 spread on the same certified stone. MOH London lists it at $1,196. 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.
