The Mineral Rosasite

mineral rosasite


Rosasite, a carbonate mineral, has little potential for being used as an ore of copper and zinc. Its chemical composition is Copper, Zinc Carbonate Hydroxide, having a copper to zinc ratio of 3:2. It is found in secondary oxidation regions of zinc-copper deposits. Fibrous rosasite crystals in blue-green color are generally located in globular aggregates.

Chemical Formula  
(Cu, Zn) 2 (CO3) (OH) 2

Derivation of Name  
Rosasite gets its name from the Rosas mine, Italy, where it was discovered.

Rosasite is not a common mineral. It gets formed in the secondary oxidized region of copper-zinc deposits, which have been created by the reaction of zinc solutions with copper minerals. Rosasite could be of post-mine origin too. In general it occurs as crusts and botryoidal heaps or nodules. It has fibrous crystals that are found in tufted aggregates.

The gemstone uses of Rosasite include:

  • Soothing of emotions.
  • Easing the applications of Mantras.
  • Assisting access to memory.
  • Helping to realize the perfectness of the cosmos.
  • Getting personal insights.

It is predominantly found in New Mexico, Arizona and Inyo County in California, USA, Tsumeb, Rosas Mine at Sardinia, Italy; and Durango, plus Mapimi. Small quantities are also found in England, the USA, Namibia and Mexico.

It possesses an eye-catching bluish green color. Rosasite is coupled with red Limonite plus some more colorful minerals like Aurichalcite, Hemimorphite and Smithsonite. Nodules of Rosasite surely inject color to what is known as "landscape" specimens.  Rosasite may be mixed-up with Aurichalcite, (Zn, Cu)5 (CO 3 )2(OH)6, though it is typically enormous but not lamellar. Crystals of Rosasitare are harder when compared to Aurichalcite.

Generally, the color is bluish-green to green.
