About this 1.52ct lab-grown emerald diamond

This 1.52ct lab-grown emerald sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG850679590 or 850679590. Listed at 3 retailers as of October 29, 2026, with prices from £274 to £726, a £452 spread on the same certified stone. MOH London lists it at £726. 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.
