I never really thought about what sand would look like closeup. I assumed it was small chunks of smooth rock, shells and maybe glass. But, here are some exquisite closeups of what sand really looks like when magnified up to 250X. The shapes, colors and textures all vary. It's amazing and so beautiful to think this is what feels so good between our toes when we walk on the beach. I have a new respect for sand...I think I'm going to start collecting sand!
