About this 0.45ct natural marquise diamond

This 0.45ct natural marquise sits in the sub-half-carat band, graded D 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 2201070138.

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