About this 1.29ct lab-grown emerald diamond

This 1.29ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG567340504 or 567340504. Listed at 9 retailers as of October 29, 2026, with prices from £116 to £677, a £561 spread on the same certified stone. MOH London lists it at £677. 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.
