About this 1.5ct lab-grown emerald diamond

This 1.5ct lab-grown emerald sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG583333460 or 583333460. Listed at 21 retailers as of November 4, 2026, with prices from £198 to £1,040, a £843 spread on the same certified stone. Brilliant Earth lists it at £1,040. 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.
