This 0.7ct lab-grown emerald sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407932270 or 407932270. Listed at 11 retailers as of October 29, 2026, with prices from £291 to £1,416, a £1,126 spread on the same certified stone. MOH London lists it at £1,416. 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.
