I received this sand matrix from a forum member a few years ago. Unfortunately, I don't remember who I got it from. I believe it is from the southeast coast of the U.S. It doesn't contain a lot of fossils, but it sure is pretty. I have found a couple items of interest. I think the pink sand is garnet, but I'm not sure. The field of vision in the image is 1 cm.

.You can pick these stones up with a magnet so I think they are mostly garnets. Lots of different colors and shapes here. This is some of the most beautiful stones I've ever found.
