+1 from the random bonuses an item has.
+1 from the enchant bonuses an item has.
That is my understanding.... you may be able to get a 4th from the luxed +10-+12 bonuses but I don't honestly know about that.
Further note that my understanding is on PVP gear when we get it the bonuses are not limited to 1 of each per type. So if it has 3 random bonuses all 3 could be the same if you took the time to make them as such.
