Is it possible to get guns not only to gold but diamond?

How are you going with black ops 2. you know the old days when we had Black ops and it took a very long time and so much effort just to get gold camo on your guns. Well, now in the new Black ops 2 they have thought about what they should do with all the camo's and weapons and thought very hard.Treyarch has introduced a new camo all together that will stay with you for the whole game. The diamond camo it looks like this...Yes indeed that is what it looks like very stylish hey. well to get this camo you will need to have all the challenges complete for your certain gun then you will be able to unlock this diamond babe.but also you have to also have your secondary to gold then you will be able to get diamond on both primary and secondary weapons.
