5.8 x 5.4 x 2.9 cm. Bisbee is most famous for its copper-based mineral specimens, but here is an example of an iron mineral that is often ugly, but here appears in an attractive, super-lustrous botryoidal form. Collector Dave Stoudt acquired this piece at the 1987 Tucson Show for his large Bisbee suite.
2.7 x 1.7 x 1.3 cm. A DRAMATIC, KILLER thumbnail from the Charlie Key Collection and the Orange River area of Namibia. A super-sharp, pseudohexagonal, water-clear quartz crystal features an incredible, sharp, pyramidal, brick-red hematite phantom.
6 x 3 x 0.3 cm. These absolutely stunning rutile crystals are nearly 6 cm in length, and shooting straight up from a platy hematite at the bottom.
9.9 x 6.4 x 3.9 cm. Slender, gemmy quartz crystals rise from a matrix of intergrown rosettes of bladed hematite. Many of the quartz crystals have inclusions of hematite crystals inside, having engulfed them as they grew. The gently curving matrix gives this specimen a wonderfully aesthetic form.
14 x 10.4 x 8 cm. A fine specimen with classic Tsumeb stepped rhombohedral crystals included lightly with red hematite grains. This is not a coating, but an inclusion. Ex. Willy Israel Collection.
25.2 x 19.5 x 9.4 cm. A large hemispherical aggregate of solid calcite, with rich, red inclusions of hematite in the tops of all the crystals. Ex. Willy Israel Collection.
8.8 x 3.5 x 3.1 cm. Very nice well-formed Calcite rhombs covering about 80% of the matrix. Furthermore, there is a preferential coating of Hematite on only the very edges of each calcite crystal. Ex. Willy Israel Collection.
8.5 x 7.4 x 4.4 cm. A fine metallic, botryoidal hematite from Morocco.
5.8 x 5.3 x 3.6 cm. A fine calcite "pineapple" from the famous iron mines of Egremont, England. The very glassy, colorless calcite scalenohedrons, to 2.2 cm, are preferentially coated with rust-red hematite. Ex. Joseph Rawlings and Seaman Museum Collections.
7.3 x 5.3 x 5.3 cm. This specimen features a 5.5-cm calcite crystal canted at an angle, with little balls of hematite and crystals of chalcopyrite both on its surface and included just inside the surface of the crystal. The two minerals are sprinkled on the milky calcite matrix as well.
7.7 x 4.3 x 2.1 cm. A unique and unusually shaped doubly terminated quartz crystal from recent finds at the Orange River of South Africa. This glassy, highly lustrous, flattened, euhedral crystal is preferentially and dramatically included with rust-red hematite. Ex. Charlie Key.
5.8 x 2.2 x 2.2 cm. Sparkly quartz crystals have grown on a floater crystal of ilvaite, which has been partially replaced and also coated with hematite.
2.6 x 2.5 x 2.3 cm. Hematite has pseudomorphed a perfectly-formed octahedral crystal of magnetite - with interesting terraced epitaxial faces.
6.2 x 3.5 x 3.0 cm. A superb, old-time cluster of gorgeous, hematite-tinted calcite scalenohedrons from the famous Stank Mine and John Ydren Collection. The sharp, water-clear crystals reach 2.5 cm.
9.3 x 3.5 x 2.8 cm. This near-floater is doubly-terminated, with the largest crystal having multiple basal terminations. The glassy and translucent crystal is included with hematite which has given the specimen an incredible fiery orange color. Ex. Charlie Key Collection.
