About this 13.05ct natural princess diamond

This 13.05ct natural princess sits in the over five carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2191862530.

If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
