13.7 x 2.5 x 1.9 CM (cabinet)
A large, quite old German Hematite of the type we call "pencil ore" but are also called "swords" . This has the original label from the Philadelphia Acadamy collection with notation of the donor, John Hartman (1840-1910). We know that Hartman made bequests to the Acadamy between 1879 to 1905. Three older affixed collection numbers are on the specimen as well, so it is certainly much older than that. It is likely there was some confusion regarding the locality as it is listed as Glaskopf, Saxony, probably being copied from a small nearly illegible label on the specimen. At one time the word Glaskopf referred to a form or habit of Goethite and Hematite and not a locality that we know of. Regardless of that detail, this is a nice and sizable example of an early German Hematite with classic form, color and provenance.
Hematite with Rutile
Cavradi, Tavetsch, Grissons
3 x 1.7 x 1.4 CM (thumbnail)
Swiss Hematite with very well formed blades standing on minimal matrix. A close exam shows some tiny but brilliant red Rutile crystals on some faces. A nicely composed thumbnail (or toenail) that looks good from both sides. In excellent condition, a very lustrous and classic Alpine specimen. This specimen was originally labeled as from St Gotthard, but we are assured this habit with the epitaxial Rutile is unquestionably from Cavradi and is distinctive for the Cavradi Gorge.
Hematite - Goethite iridescent
Covington Prospect, Alleghany County
9.9 x 2.6 x 1.4 CM (cabinet)
Vivid colors and fine form on this older specimen from the Les Hitchings collection, obtained by trade in 1966. A botryoidal stalactitic form this piece comes from Covington, Virginia from an old Manganese prospect near the Peters mountain site which also produced this sort of Hematite. This is a super esthetic piece viewed from any angle and a killer for the location. The name Turgite is commonly used for the colorful "limonites" that are mixtures of Goethite and Hematite usually with the Goethite partly or fully altered to Hematite and showing iridescence. Impossible to find anything like this today on the market, a colorful and choice Virginia specimen.
Hematite (iron Rose) on Adularia
St Gotthard, Central St. Gotthard Massif, Leventina
5.3 x 5 x 2 CM (small cabinet/ large miniature)
A bright single flower of bladed Hematite contrasting nicely with sparkling Adularia crystals. An older "Eisenrose" this is sharp and displays well, the main rose being 1.3 CM across. A classic Alpine specimen when these are a bit larger they can be incredibly costly. This is a fine smaller piece (far more affordable) and could be trimmed to a fine thumbnail if desired.
These Hematite pseudos when they are good have an incredible form. This specimen is one of the very best I have seen, perfect, complete all around and with well developed faces. Marcasite is an unstable mineral that can decay over time but these pseudos are perfectly stable. The detail of growth is perfectly preserved and presented on all the faces and the form looks like a leaf. These are sporadically available but very few are of this size and sharp development. A superb pseudomorph and an very esthetic piece.
Hematite pseudo after Magnetite
Payun Volcano, Altiplano de Payun Matru
4.2 x 2.2 x 1.7 CM (miniature)
Late Summer 2018
The form of these Hematite pseudos is simply incredible. This is a complete floater, no damage or contacts, sharp, metallic luster and very well detailed. One of the best mineral finds of the past several years the Payun Volcano mineralogy is fascinating and the morphology of the better crystals like this is exceptional.
Hematite- twinned pyramidal crystals
Hadley Bay, Vicroria Island, Inuvik Region
9.7 x 5.8 x 5.3 CM (cabinet)
A fine specimen of this unusual habit from Northern Canada found over 15 years ago. These have sometimes been labelled as Hematite Pseudomorph after Calcite (they are not) since the Hematite is somewhat shaped like a Calcite scalenohedron. The crystals reach to 2CM and some show complex growth and twinning. Very bright luster and better in person, the best example I have seen.
Hematite coated by Andradite
N'Chwanning II Mine, Kalahari Manganese Filed
Northern Cape Province,
5.8 x 3.4 x 3.2CM (cabinet)
A Kalahari classic, sharp and lustrous Hematite crystals are nearly covered with blood red Andradite Garnets. In very good condition the only damage to note is on the outer edges. From a find made over 20 years ago, these coated Hematites are now rarely seen on the market. In person the red hue is deeper than the photos show. A few areas of mirror bright Hematite are exposed where the garnet layer has come off. From the famed NChwaning mine that is more famed for the great Rhodochrosites. A very desiable specimen of this unique find.
