Silicate minerals
Silicate minerals are the most important minerals, because they are up to 80% of all minerals on Earth. They are used mainly in industry and jeweliry.
The main element of the silicate minerals is (Si). He is bind usually with other elements - metals and non-metals (as iron, manganese, but also gypsum and oxide).Known elements from the binding of Si and Oxide are the quartzites - SiO2 (Silicium dioxide), but they are part of the oxide minerals group, some scientist and mineralogists consider quartzites as part of the silicate minerals group.
Silicate minerals
Labradorite
Info: Labradorite is hard solution of albite (30 – 50%) and anorhite (50 – 70%). It usually grows in pegmatite poor on silica. Labradorite has blue-green color, made from his leaf structure and fine grown titanite, magnetite and ilmenite metals inside the mineral.

Info: Chrysocolla is amorphous hard solution of silicic acid and copper silicate, where copper is often replaced by aluminum or iron. Those metals are the reason for that this mineral changes his color from green or blue to brown. Chrysocolla can form translucent aggregates with wax to glass luster...
Info: Muscovite is the name of various mica minerals, which are with good side fissure and crystallizes in tabular shapes. It can be chipped into elastic and sometimes even transparent leaves. Typical for mica is the silver pearl luster. Variations of muscovite include paragonite, glaukonite,...

Info: Talc is the softess known mineral. Talc cannot be found in well grown crystals, he is mostly found in various agregates. Talc is usually white, but it can be grey or greenish. Talc is translucent in thin layers.
How to recognize: Talc feels greasy. It cannot be dissolved in acids or...
Info: Apophylite can often be found in well grown crystals with different habitus. It can create crystals with tetragonal bypyramids. The crystals of Apophylite can grow up to enormous sizes. Apophylite can have different colour, most favoured are pink, green and blue crystals. It can be...
