This 0.42ct lab-grown emerald sits in the sub-half-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG688517754 or 688517754. Listed at 14 retailers as of October 27, 2026, with prices from £61 to £555, a £494 spread on the same certified stone. MOH London lists it at £555. 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.
