This 1.07ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407981580 or 407981580. Listed at 11 retailers as of October 31, 2026, with prices from £485 to £3,133, a £2,647 spread on the same certified stone. MOH London lists it at £3,133. 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.
