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 LG400943045 or 400943045. Listed at 11 retailers as of October 25, 2026, with prices from $700 to $3,593, a $2,893 spread on the same certified stone. MOH London lists it at $3,593. 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.
