The Mineral Linarite

Linarite is a rather rare, crystalline mineral, which collectors value for its abnormally strong, chaste blue color. It gets formed by oxidation of copper sulfides like chalcopyrite and Galena.

Chemical Formula  
PbCu [(OH) 2|SO4]

Derivation of Name  
It gets its name from its locality. German linarit, from Linares, Spain, its locality, + German -it -ite

Occurrence         
Linarite is found as monoclinic prismatic to tabular crystals and asymmetrical masses. Though often confused with Azurite, it does not react with dilute hydrochloric acid like Azurite.

Gemology  
A mere look at the mineral prompts most collectors to have it among their collection.

Source 
Prominent occurrences are Tiger, Butte, Arizona, and Montana, USA; Argentina, Leadhills, Scotland and Spain.

Mineralogy  
Linarite has a brilliant blue color. This stunning and fairly rare mineral is generally found as crusts of tiny crystals. Though the crystals may be small, their color is always intense. This mineral can easily be taken for linarite. However, linarite does not show any reaction with dilute hydrochloric acid. Linarite is produced as a result of oxidation of copper and lead minerals like chalcopyrite and galena and its minute sparkling crystals, posses an impressive color.

Color           
Color is bright blue.

Density      
5.35 -5.5 g/cm3                       

Mohs hardness      
2.5
