Rhodonite is colored pink by the presence of manganese. The contrasting black lines make for dramatic cabochons and some interesting landscape patterns. Although rhodonite has a reputation of being hard to polish, it usually polishes nicely with diamond, or chrome oxide.
NOTE: Rhodonite with Cuprite is a more crystaline form of rhodonite and therefore tends to have fractures. This material should be not be cut with coarse wheels and care must be taken not to put too much stress on the stone when cutting and polishing.
