About this 0.52ct lab-grown emerald diamond

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 £208 to £1,041, a £833 spread on the same certified stone. MOH London lists it at £1,041. 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.
