I've noticed that Ornaments aren't in the Collection tab and for example Catalysts doesn't need to be in the collection tab since they're "attached" to the weapon/armor itself, but ornaments aren't in the Collections tab and takes place in the cosmetics inventory area and vault. On "X" on Xbox One it says "Unlock" what does that mean? I've "Unlocked 1 ornament" once and never found it again.

When an ornament is unlocked it's removed from your inventory and becomes available in whatever exotic it was for.
