This 0.78ct lab-grown emerald sits in the just-under-one-carat band, graded J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407932265 or 407932265. Listed at 11 retailers as of October 27, 2026, with prices from £357 to £1,636, a £1,278 spread on the same certified stone. MOH London lists it at £1,636. 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.
