About this 1.54ct lab-grown emerald diamond

This 1.54ct lab-grown emerald sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG598338717 or 598338717. Listed at 13 retailers as of November 4, 2026, with prices from £155 to £783, a £628 spread on the same certified stone. Brilliance lists it at £783. 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.
