About this 1.02ct lab-grown emerald diamond

This 1.02ct 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 LG589314433 or 589314433. Listed at 22 retailers as of October 26, 2026, with prices from $167 to $866, a $699 spread on the same certified stone. MOH London lists it at $866. 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.
