This 1ct lab-grown emerald sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG436045925 or 436045925. Listed at 11 retailers as of October 29, 2026, with prices from $1,029 to $6,976, a $5,947 spread on the same certified stone. MOH London lists it at $6,976. 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.
