About this 1.03ct lab-grown emerald diamond

This 1.03ct 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 LG581334704 or 581334704. Listed at 14 retailers as of November 4, 2026, with prices from £122 to £988, a £866 spread on the same certified stone. Do Amore Diamonds lists it at £988. 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.
