A friend lunched with me yesterday and I shared with her about my love for fountain pens. After I told her about metal nibs, she wondered why diamond, regarding the hardness of a nib, can't be used for such purpose by tradition... so can we break the old rule and use other materials, like diamond, as pen nib? What do you think?

Other materials can be used, but the material would need to fulfill some requirements.
Diamond was experimented with as tipping material, but, it burned up too easily to be welded, and when it was set, the setting wore off quickly.
There is no real rule as to what material can be used. It just needs to fulfill certain requirements so as to be practical for use as a nib.
Also, glass was once used. It worked well for the most part. They looked nothing like the nib you are used to seeing though!

There are processes now where a thin layer of man-made diamond can be deposited on the surface of a metal. This is more of a coating than a recognisable diamond, and it's almost always black due to residual unconverted carbon incorporated in the diamond lattice.
I have not heard of this process being used for nibs, but I cannot see why it couldn't be used. The current industrial applications for it are similar in some ways; poorly lubricated, highly abrasive, sliding contact applications. I cannot remember the name of the process, but I saw it described in the UK 'Eureka' trade magazine. I suggest you patent the application for nibs!
