About this 1.06ct lab-grown marquise diamond

This 1.06ct lab-grown marquise sits in the classic one-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.
