This 1.02ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407981520 or 407981520. Listed at 10 retailers as of October 29, 2026, with prices from €537 to €3,260, a €2,723 spread on the same certified stone. MOH London lists it at €3,260. 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.
