What is Rhodonite? 

Rhodonite takes its names from the Greek rhodon, meaning “rose”. It is a source of manganese and is relatively widespread, but it is usually mined as a semi-precious gem and ornamental stone. It is typically a pink color; however, material streaked with black veins is also favored by carvers and cutters. Massive rhodonite is relatively tough, and so is excellent for carving; it is primarily cut en cabochon for gems and as beads. Transparent crystals are sometimes found, but they must be faceted with great care, and are strictly for collectors.
