About this 0.7ct lab-grown emerald diamond

This 0.7ct lab-grown emerald sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG400942185 or 400942185. Listed at 11 retailers as of October 26, 2026, with prices from $521 to $2,529, a $2,008 spread on the same certified stone. MOH London lists it at $2,529. 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.
