SET 54 UNITS
Siderite is a fascinating mineral, known for being an important source of iron (FeCO3?). While it often appears in brownish or grayish tones, its luster can be quite attractive.
This mineral forms in a wide variety of locations around the world, from the Earth's depths in hydrothermal veins to ancient lake beds and swamps. Its presence tells us geological stories of how iron has concentrated over millions of years. It's a silent witness to the processes that shaped our planet.
