8.4 x 6.5 x 4.8 cm. A 3-dimensional, fine specimen of splendent, mammilliary, black to reddish-brown hematite of classic style for the old English locales from the 1800s. But it is from Morocco. Besides being smaller than the old English specimens, it is more lustrous than most of the English hematites. Ex. John Sobolewski Collection.
11.0 x 10.0 x 5.3 cm. Blocky, translucent and lustrous, hematite-tinted calcite rhombs to 3.7 cm are aesthetically strewn across the gossan matrix crust of this fine cabinet specimen from recent finds at Santa Eulalia, Mexico. All of the large rhombs are pristine.
7.7 x 3 x 1.9 cm. An interesting combination of four doubly-terminated Quartz crystals, included with Hematite. Each Quartz crystal is sharp, pristine, very lustrous, and gemmy. Ex. Charlie Key.
3.6 x 2.5 x 2.2 cm. A resplendent set of Hematite crystals with a gemmy calcite crystal rising beautifully out of the Hematite, all on a Calcite base. The Hematites have a lovely and interesting complex form, and superb mirror-like luster. The largest of the crystals is 2.3 cm across. Ex. Charlie Key.
Flattish, intergrown plates of showy silvery hematite - classic old material from this island! ex. Dr. Gary Hansen dealer stock and not shown since early 1980s. 7 x 5 x 2 cm
18.5 x 3.2 x 2.5 cm. A bizarre growth of nature, these strange hematite formations come from just a few of the worlds iron mining districts. This is a particularly elegant example, in a good size - most are bigger and clunkier, or smaller. It comes from the historic mining districts of upper Michigan, and was formerly in the William Pinch collection.
A classic and excellent old-time English specimen of very sparkly, black specular hematite crystals on massive hematite matrix from the iron mining district of Cumbria. 9.3 x 5.4 x 4.7 cm
2.9 x 1.9 x 1.7 cm. A classic Cavradi hematite specimen of splendent, parallel-growth hematite blades on a bit of starkly contrasting matrix. The hematite blades have interesting, stepped-growth faces and one side of the piece has embedded gemmy, wine-red rutile crystals. Ex. Jaime Bird Collection.
7.3 x 6.5 x 4.4 cm. Splendent, metallic hematite crystals comprise this fine specimen from the famous iron mines of the Elba Island. The crystals have fascinating, stepped-growth faces. Classic material from this ancient locale in a good sized specimen. Ex. Tarnowski Collection.
7.5 x 4.6 x 2.8 cm. A striking and very pretty, 3-dimensional specimen of two generations of calcite crystals included with variable shades of red hematite microcrystals from one of the famous mines at Santa Eulalia, Mexico. The three large, to 1.5 cm, partially included, transparent calcite rhombs really highlight this fine piece, which reminds me of the famous copper-included calcite crystals from Onganja, Namibia. Ex. Wesley Stark Collection.
4.7 x 3.3 x 2.3 cm. An unusual fluorite locality. Here we have sharp quartz growing out of the fluorite - usually it’s the other way around. Ex. Harold Urish Collection.
3.6 x 3.1 x 2.3 cm. Park and Teller Counties in Colorado are best known for producing some of the most magnificent Amazonite specimens in the world. There aren't many species associated with the Amazonite, mostly Quartz, Albite, Fluorite and sometimes Hematite. The majority of the Hematite specimens from this area are often found as pseudomorphs after Siderite. This particular specimen features a very attractive, excellent, sharp, aesthetic rhombic crystal of Siderite which has been replace by Hematite and is associated with golden-brown Goethite and minor contrasting pink Microcline. The specimen was collected by Richard Kosnar on May 28 1982 while on a collecting trip with his good friend Erberto Tealdi (former editor of Rivista Mineralogica Italiana). According to Rich Kosnar's label that accompanies the piece, it is very rare to find both Goethite and Hematite together, and this particular association is unique to the Lake George area of Colorado. A very attractive, and hard to find Hematite pseudomorph association specimen. Ex. Richard Kosnar Collection.
10.3 x 9.0 x 6.0 cm. Sharp, glassy, translucent, hematite-included calcite rhombs to 4.0 cm are richly and very attractively scattered all around on the mounded matrix of an earlier generation of tiny, sparkly, hematite-included calcite scalenohedrons on this fine, complete-all-around and pristine cabinet specimen from recent finds at the mines of Santa Eulalia, Mexico.
4.4 x 4.2 x 3.5 cm. A quite remarkable combination piece from the Wessels mine. The gemmy 3.5 cm Calcite, which has excellent luster and deep orange-red fluorescence in the core, is seemingly impaled on a super-lustrous, complex 4 cm Hematite. Exceptional and unusual. For color and interest, there is a layer of brilliant micro Andradites that create a sparkly druse on the Hematite. The stark symmetry is dramatic, as well. Ex. Charlie Key.
5.5 x 4.8 x 2 cm. A beautiful combination of deep-red, lustrous Andradites, mirror-like Hematites, and gem-clear Calcites. The best Hematite has a superb, lustrous face 1 x 1 cm, and it is draped incredibly by a layer of Garnets, like a shawl. The largest of the gemmy Calcites is about 1.3 cm long and sits right in front of the largest and best Hematite. All draped, in part, by all these great 1-2 mm Andradites. Ex. Charlie Key.
