The now closed Millington Quarry is over 100 years old (it opened in 1895). Starting in the late 1970's the quarry reopened and started producing a large number of specimens. This piece has several pale greenish color radiating spherical aggregates of Pectolite measuring up to 2.1 cm with prismatic Apophyllite crystals on basalt. There is also one small gray-tan Calcite crystal inside the vug of Pectolite.
