Limonite is an iron oxide that is often formed in shallow marine sediments. Limonite is actually not scientifically considered to be a true mineral. It does not have a definitive chemical formula or crystal structure, you generally see limeonite coating other minerals. When this occurs it is known as a pseudomorph. It has a medium hardness of 4-5.5. Limonite has been used throughout history as a pigment to create the color ocher & still continues into today. 
 
I love these small pieces. Personally, I like to take multiple in one hand & twirl them around like David Bowie in Labrynth. They make such a beautiful noise that it instantly soothes me. 
 
Metaphysically, limonite is believed to help ground as well move persons being toward stability. It also is known for being a stone of intuition as well!
