About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407915500 or 407915500. Listed at 6 retailers as of October 25, 2026, with prices from £829 to £1,648, a £819 spread on the same certified stone. MOH London lists it at £1,648. 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.
