Diamond Camouflage

The Diamond Camouflage is a hidden camouflage in Call of Duty: Black Ops II multiplayer. It is unlocked for every weapon in its category after all the weapons in that category have Golden Camouflage unlocked.

It appears to be combined with the Golden Camouflage, with the gold covering the parts of the weapon that the other camouflages do not cover while the diamonds are applied to the parts of the weapon that every other camouflage cover.
