This 3ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG828671575 or 828671575.

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.
