About this 1.23ct lab-grown emerald diamond

This 1.23ct lab-grown emerald sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG625454368 or 625454368. 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.
