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 very-good cut grade and certified by IGI. Listed at 6 retailers as of November 5, 2026, with prices from £109 to £481, a £372 spread on the same certified stone. Diamond Exchange Canada lists it at £481. 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.
