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 LG407998496 or 407998496. Listed at 12 retailers as of October 29, 2026, with prices from $710 to $4,171, a $3,461 spread on the same certified stone. MOH London lists it at $4,171. 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.
