Dims: 2.4" x 2.1" x 1.4" (6.1 x 5.4 x 3.6 cm)

Wt: 5.98 oz. (169.4 g)

Chihuahua, Mexico

This specimen consists entirely of part of a botryoidal crust of Hematite nodules of the variety sometimes called kidney ore. These nodules are heavily intergrown, so determining their mean size is difficult. However, they have excellent form and have been polished to accentuate their detail. All have a dark gray coloration and a dull metallic luster. Areas of their cross-section show a densely compact and finely fibrous, radiating pattern (see the close-up image). The underside of the specimen shows an irregular, amorphous surface that is slightly coated with a thin layer of rust.

Chihuahua, Mexico

A botryoidal crust of "kidney ore" Hematite constitutes this Mexican specimen. The thickness of the crust varies considerably, ranging from 0.2 - 0.6" (0.5 - 1.5 cm) and is composed of intergrown Hematite nodules that have been polished to show off their dark gray color and dull metallic luster. The cross-sections of these nodules show compact, fibrous, and radiating tendencies (see the close-up image), and the surface of their underside shows some warped botryoidal and almost crystalline form.. There is a small amount of a dull, brownish rock attached to the underside which may have been stained by the rust that stains the rest of this surface.

Wt: 1.6 oz. (46.4 g)

Chihuahua, Mexico

This small and simple specimen consists of part of a crust of reniform Hematite, commonly known as "kidney ore". Each of its rounded, intergrown nodules is made up of countless fibrous needles that do not exceed 0.3" (8 mm) in length, and are easily visible on the sides of the crust; these crystals are so compact as to be essentially intergrown into a massive form. The crusts outer surface has been polished to take advantage of the Hematite's bright, nearly metallic luster. It has a dark gray coloration and shows small areas of rust-red color and matte luster in the crevices where the nodules intersect and on the inner surface of the crust.

Chihuahua, Mexico

Part of a reniform Hematite crust makes up this small hand specimen. The intergrown nodules that make it up would measure 0.5" (1.3 cm) individually, and are in excellent condition. Their outer surfaces have been polished to take advantage of their dark gray color and their metallic luster. The color of the crust is basically gray, but portions of its outer surface have a golden-brown coloration that I usually associate with trying to polish items with a brass wire wheel. The inner surface of the crust has a dull, deep red color and a dull luster, and shows slight evidence of some tiny crystals. Its cross-section shows the almost compact, fibrous and radiating habit that this material has.

Hunan Province, China

Several clusters and many loose blades of Hematite rest among the quartz prisms that extend from this specimen. These Hematite clusters are generally in good condition, though a few show substantial numbers of broken blades. The blades range in diameter from 0.2" (5 mm) to 0.7" (1.8 cm) and show an uneven, round form. However, they are generally uniform in this respect. All are extremely thin- they do not appear to exceed 1 mm in thickness. They have the standard dark gray color and dull metallic luster of Hematite, and appear to have formed prior to the formation of the quartz crystals that accompany them. Most of the quartzes are broken, but those that are intact reach a maximum length of 1.5" (3.8 cm). They are very well-formed and are colorless, transpa

Wt: 3.55 oz. (100.7 g)

Hunan Province, China

This delicate specimen consists of several Hematite "roses", which are slightly radiating clusters of thin bladed crystals. These crystals do not exceed 2 mm in thickness, but achieve diameters of 0.8" (2.0 cm). They are in moderately good condition, as the three most exposed (and largest) clusters are noticeably damaged so that most of the crystals therein are likewise damaged. There are several smaller clusters, however, that are not damaged and in excellent condition. Though most of the Hematite blades are rounded and heavily intergrown, there are a few that show the hexagonal tabular form of this species. All have the dark gray color and dull, nearly metallic luster of Hematite. They are accompanied by at least 10 prismatic quartz crystals that are in excellent condition and have good hexagonal form. The quartzes are colorless, transparent, clear and have the standard vitreous luster. An equal number of quartz crystals are broken and incomplete. The base rock of the specimen appears to be made of quartzite, and is lightly interspersed with more Hematite blades.

Hunan Province, China

At least 20 intergrown Hematite "rosettes" rest on the granitic host rock of this large hand specimen. These "rosettes" are in generally good condition and measure up to 0.8" (2.0 cm) in diameter. Each rosette is made up of many intergrown rounded Hematite blades. Their hexagonal tabular form is moderately good, as none have a definite hexagonal shape, but their edges are very sharp, and their faces are reasonably smooth, possessing a matte-to-dull-metallic luster. The clusters generally appear black in color, but their faces are a dark gray. The Hematites are accompanied by several intergrown quartz crystals that reach lengths of 1.8" (4.6 cm), are in moderately good condition, and have excellent hexagonal prismatic form. The base rock appears to be made of an almost granitic material that is heavily interspersed with broken Hematite and quartz crystals.

Arzanah Island, near Abu-Dhabi, United Arab Emirates

This tiny specimen consists of two intergrown Hematite crystals. The smaller crystal has visible dimensions of 2 x 1 x 1 mm and is mostly intergrown with the larger crystal, whose dimensions make up most of the piece as a whole. They are in very good conditon, showing only a very tiny amount of damage on each termination, and have excellent trigonal scalenohedral form. The large crystal is doubly-terminated and has well-defined edges and striated but clean faces that possess a slightly iridescent, dull metallic luster. They have the standard dark silvery-gray color of Hematite and are, of course, opaque. There is no host rock present. As far as I know, this locality is the only known producer of scalenohedral Hematites.

Though this Hematite scalenohedron may appear to be damaged upon first glance, it is actually in excellent condition. It has excellent form and is double terminated, though one termination is truncated by a small, nearly basal face. It has well-defined edges and generally clean faces, though one shows some form-related pitting. It has the standard dark gray color and dull metallic luster of its kind, and each face shows a very subtle, colorful iridescence. There is no host rock present, of course.

Cole Shaft, Bisbee, Arizona, U.S.A.

This small hand specimen consists of a thin, colorful crust of a variety of Hematite known as Turgite which coats a manganese "wad" base. This crust is completely massive and so thin that only its color shows that it is there. Blue and green hues are dominant, though there are noticeable areas of violet and red coloration, also. Resting atop the Turgite crust are 2 cerussite crystals. Both of these crystals have formed incomplete cyclic twins.

Cole Shaft, Bisbee, Arizona, U.S.A.

A very thin crust of Turgite, a hydrous variety of Hematite, coats the manganese oxide base of this small hand specimen. The Turgite shows no crystal form, but is easy to see due to its bright coloration against the black base. Its coloration ranges from red to yellow to green to blue, and many shades between them. Resting on the Turgite crust are several cerussite crystals, at least 2 of which are twinned. They are in good condition and have excellent orthorhombic prismatic form.

N'Chwaning Mine, Kuruman, South Africa

This specimen consists of at least 3 incomplete, partly-intergrown Hematite crystals. These crystals appear to be very heavily damaged, but only a small portion of this damage occurred after the piece was mined- most of the breakage surfaces show definite partial-healing. The largest crystal has dimensions of 1.5 x 1.2 x 1.2" (3.8 x 3.0 x 3.0 cm) and shows partial but very good hexagonal form- though normally bladed, these crystals are nearly thick enough to be prismatic. Where intact, they have well-defined edges and often striated but clean faces. The largest crystal appears to be an inter-penetration twin. All have the classic dark gray color and metallic luster of their species. There is no host rock present, and the piece is hot-glued onto a flat acrylic base.

Minas Gerais, Brazil

This interesting Hematite specimen consists of a piece of "kidney ore", a variety of Hematite that takes on a reniform habit. Its outer surfaces are generally rounded, smooth and undulating, though the outermost layer of material has chipped away in a few places. It shows the standard dark gray color and metallic luster on its outer layer, and a duller luster and reddish color on the exposed inner layer and in places on its underside. The underside is interesting in that a layer is visible that denotes a compact, fibrous habit. There is no base or host material present.

Creole Mine, Beaver County, Utah, U.S.A.

The Hematite in this hand specimen takes on the form of weird pseudo-crystals that are apparently formed through the intergrowth of countless thin, tabular crystals. Though many of the crystals are isolated and easy to see, damage is rather widespread, marring their shapes- even those that are well-protected and intact do not show any form of hexagonal outline. All have the dark, silvery-gray color and metallic luster of their species. The base in which they are embedded is made up of scores of heavily intergrown and water-worn quartz crystals that are milky-white in color and translucent at best.

Sierra Mojada, Coahuila, Mexico

This large cabinet piece consists almost entirely of massive Hematite. Though showing some obviously crystalline habits, no discernable crystal form is evident. Most of the material has a dull luster and the standard black, brown or gray color, but part of the surface is coated with a thin layer of the Hematite variety Turgite, which shows a colorful iridescence. A crust of white calcite covers a small portion of the piece- it is heavily worn or etched.

Sierra Mojada, Coahuila, Mexico

A chunk of mostly massive Hematite comprises this cabinet piece. Close examination will show many semicrystalline or crystalline faces on the surface of the specimen, though no actual crystals are present. The material shows mostly a black or brown coloration and a dull luster, but has a gray color and submetallic luster where semicrystalline formation has occurred. A thin layer of Turgite, however, has caused an intense iridescent coloration on much of its surface- these colors span the visible spectrum. There are no other minerals or materials present.

Sierra Mojada, Coahuila, Mexico

Among the massive Hematite that makes up most of the mass of this cabinet piece are some obvious crystalline formations. No complete crystals are present, however. This crystalline material has a gray color and a submetallic luster; portions of the massive material also share these traits, but most of it shows a duller gray, brown or black color and a dull, matte luster. However, a thin layer of Turgite that coats some of the massive material has given it an intense and colorful iridescence. There is no other material present on the piece.

Sierra Mojada, Coahuila, Mexico

This large display specimen consists almost entirely of massive Hematite, but contains a few obviously crystalline formations, including a few thin blades in a hollow that I cannot identify- their form certainly is not conducive to Hematite. The material generally has a brown, black or gray color and a dull luster, though a few small spots are submetallic. However, the piece has a heavy Turgite coating over a large portion of its surface, giving it a beautiful iridescent color. Several small patches of weathered white calcite rest on the Hematite.
