About this 3.55ct lab-grown radiant diamond
This 3.55ct lab-grown radiant sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI. 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.
