About this 4.51ct natural cushion diamond

This 4.51ct natural cushion sits in the three to five carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2215973994.

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