This 0.42ct lab-grown emerald sits in the sub-half-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG710558020 or 710558020. Listed at 16 retailers as of October 29, 2026, with prices from £67 to £612, a £545 spread on the same certified stone. MOH London lists it at £612. 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.
