Just tumbled into minerals... This iron-based mineral hematite' is beautiful: it can have the shape of a kidney, or a skull. The Greek word 'aims' means 'blood'. In Dutch we call this stone 'glaskophematiet.
Malachite is another , green and very common copper mineral, with a widely variable habit. Typically it is found as crystalline aggregates or crusts, banded in appearance. Until the 18th century, the malachite mineral wow used for its green color by painters...
For me it's all about the natural shape! Great stuff! Love it!
