About this 0.42ct lab-grown princess diamond

This 0.42ct lab-grown princess sits in the sub-half-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG770688811 or 770688811.

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.
