This specimen displays one large and several small gyrolyte clusters on a matrix composed largely of colorless transparent crystals. The gyrolite is subtly green, and a loupe reveals that the spherical clusters are composed of rounded books of thin translucent crystals. I believe that the matrix mineral is apophyllite, as the crystals are complex, even rounded, but the common form is cubic, and the crystals have faint striations.
