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 LG407981441 or 407981441. Listed at 10 retailers as of November 4, 2026, with prices from $754 to $4,571, a $3,818 spread on the same certified stone. MOH London lists it at $4,571. 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.
