This is what I have as it stands, I cant get that diamond in the center

Im trying to make a cover for something like my friend made (here's his) but with a shade of blue, so I got the shade of blue I wanted, selected gradient and the diamond option and selected white as my color, but when I try to make it, nothing happens, it says its doing something on the history but I cant visibly see anything. I'm starting from just a solid color and trying to get the same effect as seen in his, how do i do that?
