Meckley Quarry, Bedford, Pennsylvania, U.S.A.
This large hand specimen consists of several veins of crystalline and massive Strontianite that run through a shale matrix. One face of the specimen is partly covered with many intergrown clusters of tiny, radiating Strontianite spikes that show moderate damage. None of these exceeds 3 mm in length, so their orthorhombic prismatic form is difficult to study without magnification. They do appear to have goood form, though, and they have a milky-white color and a pearly-to-waxy luster. The more exposed of the clusters show good translucence. The Strontianite clusters are accompanied by random, tiny calcite crystals and possibly some celestites.
