About this 4.08ct lab-grown oval diamond

This 4.08ct lab-grown oval sits in the three to five carat band, graded J 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.
