About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG500148302 or 500148302. Listed at 10 retailers as of October 29, 2026, with prices from €222 to €868, a €647 spread on the same certified stone. MOH London lists it at €868. 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.
