DSC_1523_Rhodonite freeform
The last of the Sunday foursome. This is a big boy, made from a square-ish, uneven slablet that had been laying around. It is almost 1cm this with a 3mm girdle!
This is a rock, since it is a melange of different minerals
The pink is Rhodonite (MnSiO3)
The black is manganese oxide (MnO)
The white is likely wollastonite (CaSi03)
The gray and brown are probably bustamite (a mix of rhodonite and calcium oxide)
