About this 1.01ct lab-grown emerald diamond

This 1.01ct 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 LG407998493 or 407998493. Listed at 11 retailers as of November 4, 2026, with prices from $843 to $5,112, a $4,270 spread on the same certified stone. MOH London lists it at $5,112. 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.
