What is silver mineral used for?
It is used for jewellery and silver tableware, where appearance is important. Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries.
What is the crystal shape of silver?
Native silver is usually without a characteristic crystal habit. When it forms in the open spaces of pockets and fractures, some interesting crystal habits sometimes develop. The crystals are rarely the cubes, octahedrons, and dodecahedrons expected of an isometric mineral.
Is silver transparent translucent or opaque?
Metals like gold and silver, and some minerals containing metals, are opaque – you cannot see though them at all. In the pictures below, the calcite is transparent, while the gypsum is translucent and the gold is opaque.

Silver (Ag) has a bright, metallic luster, and when untarnished, has a white color. It is rarely found in its native form. Silver can be found combined with a number of different elements such as sulfur, arsenic, antimony or chlorine to form a variety of minerals and ores, such as argentite, chlorargyrite, and galena.
What mineral is opaque?
Common opaque minerals are graphite, oxides such as magnetite or ilmenite, and sulfides such as pyrite. Isotropic minerals are minerals that have the same properties in all directions. This means light passes through them in the same way, with the same velocity, no matter what direction the light is travelling.
