Amicite is a hydrous sodium potassium aluminosilicate, specifically a member of the zeolite group (Coombs et al., 1997). Alberti et al. (1979) named the mineral in honor of Giovanni Battista Amici (1786-1863), Italian physicist and optician, who contributed to the development of the reflecting telescope and optical microscope.
Amicite here forms pseudo-octahedral crystals to 5 mm, scattered over earlier spheres of natrolite to 6 mm across. Crystallized amicite and natrolite covers two sides of a thin matrix. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
