Packaging: Mocking up Diamonds

I searched for some diamond nets and came across some good ones. I mocked up the ones I thought were the most interesting or closest to the staffs design.

These were just rough mock ups in paper. For my final packaging I will digitally paint my own texture on them and get them professionally printed. I need the diamond to sit on top of my packaging so I will look into how I can alter the net to suit this.

I'm wondering if I could get this printed on a metallic or shiny surface to add to the diamond affect - I will look into this.
