Beryllite is a hydrous beryllium silicate. Kuzmenko (1954) named the mineral for its beryllium content. The crystal structure and unit cell of the mineral remain unknown.
Beryllite here forms a boxwork structure replacing chkalovite; beryllite is a coffee-brown botryoidal crust. The matrix is massive albite. This specimen is from the type locality. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
