About MozartiteHide

Wolfgang Amadeus Mozart

Formula:

CaMn³⁺(SiO₄)(OH)

Colour:

Reddish brown to deep red

Lustre:

Vitreous

Hardness:

Specific Gravity:

3.63

Crystal System:

Orthorhombic

Name:

For Wolfgang Amadeus Mozart (27 January 1756 – 5 December 1791), a prolific and influential composer of the Classical era. The mineral was discovered 200 years after his death. The describing authors note 'the close association of geological and mineralogical sciences with Mozart's music, and especially with his last opera "The Magic Flute"'.

Type Locality:

ⓘ Cerchiara Mine, Borghetto di Vara, La Spezia Province, Liguria, Italy

A rare mineral in some metamorphosed manganese deposits.

Please note that many samples marketed as Mozartite from India are actually apophyllite with dense inclusions of celadonite and other clays, with no evidence for true Mozartite.
