This 1.01ct lab-grown emerald sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407945418 or 407945418. Listed at 10 retailers as of October 27, 2026, with prices from $700 to $3,839, a $3,139 spread on the same certified stone. MOH London lists it at $3,839. 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.
