Just put in a +1 jewel and calculate from there.

There are too many variables to consider to just strip naked with no pets and get an answer.

Base stats and adding jewels are not calculated the same way. Base stats are always the same and as some have already stated +10 str will always give the same results on a naked toon.

Though a +10 jewel will give everyone a different value once gear and awakes and level and everything else is taken into account

As the OP asked about adding jewels to his/her gear i don't think stripping naked to calculate base stats will provide an accurate figure when it comes to adding a jewel
