Many rounded Prehnite nodules are intergrown to form a reniform crust on the basalt base rock of this specimen. These nodules do not exceed 0.4" (1.0 cm) in diameter, and most are in good condition, though there is some noticeable damage to a few of them. All are incomplete due to intergrowth with the basalt base or each other, and their forms are good, though not close to being perfectly spherical. All are nearly colorless, with a faint green tinge and a cloudiness that may be caused by their dull, waxy luster, and are dimly transparent. Accompanying the Prehnites are two almost cubic apophyllite crystals that are colorless, transparent, and have a good form and a bright pearly luster.
