About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG536274323 or 536274323. Listed at 5 retailers as of November 4, 2026, with prices from $667 to $1,934, a $1,267 spread on the same certified stone. MOH London lists it at $1,934. 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.
