About this 1.99ct lab-grown cushion diamond

This 1.99ct lab-grown cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and I1 clarity (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.
