The way it works is this. You are essentially allotted three gems per day (not usable by you) to share with GameCenter contacts (aka "friends"). With the Dragonsai Tree, that allotment is increased to six per day. You can gift one gem to each contact on your list once daily, up to a maximum of three (or six w/ the tree). These are gems you don't have in your stockpile, they are simply available to you to gift to your Dragonvale contacts.

So, if you have contacts who do the same, your in-game gem total will increase by one when you receive the gift, and theirs will do the same. If you are "one for one" with six contacts, you will get six gems per day. If you have more contacts than that, you can't give them all a gem, but they might all give you one. In that case, you would get more than six per day but would no longer be fully reciprocating.
