Your link for more pictures does not work for me. I do like the glass backsplash tiles you are considering. I also like the small dark square tiles you show at the bottom. They relate well to the dark speckles in your granite and would look good with rubbed bronze fixtures. If you are going to trim the glass tiles I think you should use those dark square tiles on both the top and bottom of the glass tiles instead of the lighter squares in the picture above.

In the picture with the light colored squares at the top and the dark squares at the bottom, I'm kind of liking the lighter color. But the color would have to be perfect. Your link doesn't work. I don't see a picture in your post on my iPad, only a tiny square that I can click on to see a close up of your tile. This happens on my iPad. I don't know why.
