Rhodonite is a rare, manganese-rich silicate mineral that’s often used as an ornamental stone. Its color usually varies from pink to rose red to brownish red, with blackish veins. It can also be translucent to opaque in appearance. The gemstone is made of manganese silicate but it’s often combined with other elements like calcium and iron. Rhodonite’s color is stable to light, but if set in jewelry, it can be fused into brownish or black glass under a jeweler’s torch. It is a relatively rare stone and can be found in many locations around the world but only in small quantities. Read more:- Rhodonite History
