About this 1.69ct lab-grown emerald diamond

This 1.69ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG514250651 or 514250651. Listed at 10 retailers as of October 29, 2026, with prices from £371 to £980, a £609 spread on the same certified stone. MOH London lists it at £980. 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.
