Several clusters of tiny,radiating Strontianite blades rest on the white celestite base of this small hand specimen. The largest of these clusters measures 0.6" (1.5 cm) in diameter and, like the others, is in very good condition, showing little damage. Each is made up of scores of tiny blades that do not exceed 1 mm in length and probably have very good orthorhombic form, though they are too small to study even with a loupe. All have a milky-white color and a dull pearly luster, and though individual crystals may be transparent, the clusters are essentially translucent. The celestite base on which they rest shows definite crystalline tendencies, but appears to have been heavily weathered or worn, so that no actual crystal form is definable. The piece is hot-glued onto an acrylic base.
