This 0.52ct lab-grown emerald sits in the half to three-quarter carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG823640408 or 823640408. Listed at 5 retailers as of October 28, 2026, with prices from £202 to £858, a £656 spread on the same certified stone. MOH London lists it at £858. 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.
