Smithsonite is a zinc carbonate mineral sometimes referred to as zinc spar. Upon original categorisation , Smithsonite & Hemimorphite where considered the same mineral & classed under the same name Calamine. In the early 19th century the differences where discovered, the main difference being Hemimorphite is a sorosilicate & not a carbonate mineral. In 1832 Smithsonite was given an individual mineral name by François Sulpice Beudant in honor of English chemist & mineralogist James Smithson (c.1765–1829), who was founder of the Smithsonian Institution & first identified the mineral in 1802.
Until the 1880’s it was the principal ore of zinc, it was then replaced by Sphalerite. It is believed to have been used in ancient metallurgy as the Zinc component for Brass. Rarely found in well formed crystals as it most often occurs in botryoidal mass Smithsonite primarily occurs as a secondary mineral in weathering & oxidation zones of zinc-bearing ore, particularly in limestones which provide the carbonate. It is also found as replacement bodies in carbonate rocks & commonly with associate minerals such as Hemimorphite, Willemite, Cerussite, Malachite, Azurite & Anglesite. Smithsonite forms two limited solid solution series, with a substitution of iron creating Siderite & manganese substitution creating Rhodochrosite.
The varying colours in Smithsonite are created by inclusions of trace elements; green to blue from Copper, pink to purple from Cobalt, yellow from Cadmium & brown to reddish from Iron.
The truth speaker stone, Smithsonite helps one to speak their truth it opens the heart, throat & third eye chakras clearing trapped or stagnant energy. It releases & repairs damage from self oppression or feelings of unworthiness, this empowers one to stand up for themselves & assert boundaries in positive productive ways.

It is excellent for clearing the energy of tainted water & helping to restore waterways for life to flourish. This connection is great for internally washing away emotional turmoil & cleansing the body of anger, stress or high heat energies.
