About this 1ct lab-grown emerald diamond

This 1ct 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 LG380970969 or 380970969. Listed at 8 retailers as of October 28, 2026, with prices from $1,029 to $5,227, a $4,198 spread on the same certified stone. NZ Jewellers lists it at $5,227. 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.
