WebSiderite belongs to the calcite group and forms series with rhodochrosite and magnesite. Diagnostics. This stone is too soft to be cut and is hence rarely faceted as a gemstone. As it is a carbonate, it would give effervescence (bubbling) when in contact with acids; strong eye visible doubling due to the high birefringence.
Weblimonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH2O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite.
