# STR-8, $36.00 Sold!
Dims: 1.10x0.87x0.63" (2.80x2.22x1.60cm) .... Wt: 0.45oz (12.8g) .... Loc: Oberdorf, Styria, Austria
Unlike many specimens of strontianite, this one shows large crystals in radial clusters. While many of them are merely translucent, the tips of several crystals are very transparent. The color is an off-white, although much (but not all) of the browish tint is due to a thin coating of a brown mineral. The strontianite crystals have basal terminations and a (generally distorted) hexagonal cross-section, which I understand to imply that these crystals are all twins.
# STR-7, $60.00 Sold!
Dims: 1.8 x 1.5 x 1.1" (4.5 x 3.8 x 2.8 cm) .... Wt: 1.2 oz. (33 g) w/ base .... Loc: Sub-Rosiclare Level, Minerva Mine #1, Ozark-Mahoning County, Illinois, U.S.A.
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.
# STR-6, $32.00 Sold!
Dims: 1.7 x 0.9 x 0.6" (4.4 x 2.2 x 1.6 cm) .... Wt: 10 g .... Loc: Rosiclare Level, Minerva Mine #1, Ozark-Mahoning Company, Cave-In-Rock, Illinois, U.S.A.
This large thumbnail specimen consists of a cluster of heavily intergrown Strontianite crystals that strongly resembles a wheat sheaf. The crystals are not quite needle-like, but they are very thin and radiating. They are in moderately good condition, as many are broken, and reach lengths of 1.2" (3 cm). All have a rather warped, pointed orthorhombic form that is not very easy to define. Their creamy color has a considerable dull-violet tinge and their luster is waxy, and all are essentially translucent, though the tips of some may be transparent. There is no host rock present.
# STR-5, $45.00 Sold!
Dims: 5.1" x 3.2" x 2.7" (13.0 x 8.1 x 6.9 cm) .... Wt: 1 lb., 13.5 oz. (837 g) .... Loc: 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.
