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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG400933137 or 400933137. Listed at 7 retailers as of October 28, 2026, with prices from $600 to $2,292, a $1,692 spread on the same certified stone. NZ Jewellers lists it at $2,292. 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.
