Is sphalerite a rare mineral?
Is sphalerite a rare mineral?
Sphalerite is a rare gem mineral that crystallizes in the cubic crystal system and consists largely of zinc sulfide formed with variable iron, with the chemical formula of (Zn,Fe)S. Its color is usually yellow, brown, red, or gray to gray-black with high dispersion and high adamantine luster.
Is sphalerite rare or common?
Sphalerite is a zinc sulphide mineral that is quite rare in gem quality. Top grade specimens are prized for their exceptional fire or dispersion, which is higher than that of diamond.
What is the use of sphalerite?

What is the mineral sphalerite?
Sphalerite, also called blende, or zinc blende, zinc sulfide (ZnS), the chief ore mineral of zinc. The name sphalerite is derived from a Greek word meaning “treacherous,” an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore).
Is sphalerite considered a mineral a gem or an ore?
Sphalerite is a zinc ore mineral that typically contains iron. When it has a high iron content, sphalerite is an opaque black. Gem-quality material has a low iron content, resulting in transparent crystals. Due to its lack of hardness, it is mainly a collector’s gemstone.
What are some common uses of sphalerite?
Because of its high zinc concentration, sphalerite is often used in metallurgy . In addition, because of its high level of light dispersion, polished sphalerite is a beautiful showpiece for jewelry or collections. For industrial purposes, sphalerite is used in galvanized iron, brass and batteries .
What is sphalerite used for?
For industrial purposes, sphalerite is used in galvanized iron, brass and batteries. The mineral is also used as a mildew-resistant element in certain paints.
Is sphalerite a metal?
Sphalerite is the principle ore of zinc. In some localities, it occurs with significant amounts of the rare elements cadmium, gallium , and iridium , and it is also the main ore of those metals. Sphalerite is an important mineral to collectors, and some transparent varieties are occasionally faceted for collectors.
