Limonite on 3 rocks that I have found. The closeups are with my usb microscope. I wish this forum had a category for micro macro photos. Anyway 2 pics from each rock.
Very cool photos. I had some specimans like that once, I gave them to my sister when she was into rockhounding. Maybe she will give them back to me for my son. Either way at least she still has them after 20 years. Still in the family.
