First lets assume you have some level 4 gems as well as level 5 gems, since the common gem drops in D2 were flawless and not perfect gems even though perfect gems could drop. We could potentially have a maximum of 2 gems per level 4-13 for each type or 20 gems of each type. With 6 different types of gems according to the wiki (http://www.diablowiki.com/Gems), that means that we could need to have up 120 gems in storage at a time. Once again I know the stashes are supposed to be huge, but that's a hell of a lot of storage JUST devoted to gems. Add in wanting to be able to hold talismans, runes, and gear into the equation, and we would need a truly outrageous amount of storage.
Adding runes into consideration, we know currently there are 5 types and 8 levels of runes (http://www.diablowiki.com/Runestones). Assuming 3 runes to upgrade to next level (even though we don't have this confirmed yet) and that we will likely only hold onto level 6-8 runes that drop in hell mode. Thats another 20 slots to hold just level 6-7 runes of each type. While this isn't nearly as bad as the gem situation, it still eats away more storage space.
Did anyone get to see how big the storage really is during blizzcon? Will the storage of all these gems be taken care of by the Jeweler artisan? Is there just more info on this that I haven't read yet?
