About this 1.02ct lab-grown emerald diamond

This 1.02ct lab-grown emerald sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG653410144 or 653410144. Listed at 11 retailers as of November 4, 2026, with prices from £139 to £1,077, a £938 spread on the same certified stone. Do Amore Diamonds lists it at £1,077. 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.
