This 1.56ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG831682806 or 831682806. Listed at 6 retailers as of October 29, 2026, with prices from £478 to £1,420, a £942 spread on the same certified stone. MOH London lists it at £1,420. 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.
