About this 3.2ct lab-grown radiant diamond

This 3.2ct lab-grown radiant sits in the three to five carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included) and certified by IGI LG12679112 or 12679112. 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.
