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
stock #18. AX-19-437
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.
Ziller Valley, North Tyrol
6.6 x 3.9 x 2.7 CM (cabinet)
Post Tucson 2015
An Alpine classic, sharp and lustrous rosettes of Hematite scattered on a matrix that is also covered with tiny Adularia crystals. Micros of Epidote are seen as well, the specimen is really all about the roses. Excellent luster and silvery black color this Tyrolian (Austria) piece looks just like a Swiss specimen.
A big, bright metallic black complex twin of crystallized Hematite. Displays well from several angles, there is some inevitable chipping and contacts, but these are not distracting. The specimen is very complex and presents many forms with some mirror bright faces and others with very fine striations. These Brazilian Hematites rank well alongside the worlds best and are relatively very affordable.
