This 1.31ct natural princess sits in the one-and-a-quarter to one-and-a-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 5476143958.

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