About this 5.91ct lab-grown cushion diamond
This 5.91ct lab-grown cushion sits in the over five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG826658217 or 826658217. 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.
