Phosphosiderite Sphere, 3 inches in diameter.
Phosphorous and Iron combine to form this lovely lilac material from Chili. First discovered in 1858, it was miss named and did not receive its true identity until 1910. It is a healing stone thought to help upper respiratory issues.
An interesting and odd material to work! It has lots of bugs.
