This 0.52ct lab-grown emerald sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407941467 or 407941467. Listed at 11 retailers as of October 29, 2026, with prices from $495 to $2,474, a $1,979 spread on the same certified stone. MOH London lists it at $2,474. 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.
