This 1.31ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 6435442062.

Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
