When selecting a carat weight, your decision should depend on your budget, the recipient's lifestyle and size and the ring's setting.
Since large gems are discovered more frequently than small ones, they are more valuable and expensive. If a large carat weight is important and you're working within a budget, consider a diamond with a good cut, a SI1-SI2 clarity, and an I or J color grade.
If the recipient is very active or not used to wearing jewelry, consider a smaller size diamond or a setting that will protect a larger diamond from impact. Also, keep in mind that a diamond will appear larger on a smaller finger.
If you have already chosen a setting, you also need to make sure that carat weight fits the setting. You will need to request the diamond size specifications from the place you purchased the setting.
