Hey, I just saw a diamond theme made by one of the members of this site you should check out.
His name is dwizzy130 and he made a diamond theme for htc home that might be what you are looking for. I saw it in another post where he was. Look in the members section for him and look in his signature and you can click on the theme which will take you to his website where you can download. Hope this is what your looking for.
