About this 0.43ct natural marquise diamond

This 0.43ct natural marquise sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2564347854.

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