About this 1.01ct lab-grown emerald diamond

This 1.01ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG591371598 or 591371598. Listed at 20 retailers as of November 4, 2026, with prices from $257 to $1,195, a $938 spread on the same certified stone. MOH London lists it at $1,195. 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.
