I think the trick is to make a radial gradiant and put it in the bump channel, so that it sort of looks like a pyramid.

Wow! it works!
Thanks

Although I'm still confused why do I need to make a bump map of it that are set to this settings. But I'd noticed the highlight is displaced on the center when I'm previewing it on material editor.
