About this 1.21ct lab-grown emerald diamond

This 1.21ct lab-grown emerald sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG753503183 or 753503183. Listed at 12 retailers as of October 30, 2026, with prices from €105 to €1,081, a €976 spread on the same certified stone. MOH London lists it at €1,081. 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.
