The host is coarse granite; the black parts are biotite, the dark gray grains are quartz, and the white parts are plagioclase. The yellowish-brown earthy crust is dirt.

Recovered from a pocket of a Topaz-NYF pegmatite associated with S-type (Ilmenite-series) granite. Formed in the Late Cretaceous (67 Ma).

Beryl from this location was described in 1895.
