Though most of the visible crystals on this specimen show damage in one form or another, it is still a rather impressive specimen, for two reasons: its locality, and the two largest crystals on it. These two crystals grow parallel and adjacent to each other, and appear to be tangent to each other near their bases. They both measure approximately 1" (2.5 cm) in diameter and 0.2" (5 mm) in thickness. Though they are damaged, their crystal form is quite evident. However, I cannot classify it, though it must be hexagonal-based. The crystals generally are much thicker than most Hematite tablets that I have seen, and each blade shows subtle but definite curvature on certain faces. Even the largest faces are made up of smaller faces that make them appear curved. They have the standard dark gray color and metallic luster that one expects from Hematite, and show patches of iridescence on some smaller faces. There are a few small hexagonal prismatic quartz crystals among the smaller Hematite blades- these are transparent and seemingly clear, but appear almost white due to their matte luster. There is no other material, and more massive Hematite seems to act as a host rock. I find it intriguing to consider that Napoleon may have walked on the earth over this specimen during his exile!

Do you know how common Hematite is? It's SO common that we must have a pretty spectacular specimen to put on this net shop! This thing is WEIRD! I don't even know why I should call it a crystal, but that's what it is. First, it's hollow; it looks like it was a coating for a long, prismatic crystal that moldered away. Looking down along its length one can see it's rhombohedrally shaped, and looking at its sides, a hopper-crystal effect is clearly noticeable.

We consider this to be the best single hematite crystal that we've ever seen, barring its lack of completeness. Its thick, hexagonal tabular shape is very clean and well-defined, with the classic Hematite dark-metallic luster. If you're looking for an exceptional crystalline example of Hematite, this piece is a viable option!

I would say that this Turgite specimen "has some heft"- it weighs in at over 3/4 lb. Where there is no iridescence, the black material has a dull luster, with some areas appearing to have spots of "rust" on them. The iridescent areas have colors that span the visible spectrum and a submetallic to a metallic(occasionally!) luster. There is no visible matrix, but one area has a white, powdery substance on it that seems to have occurred with the other material. I love the iridescent color- it reminds me of the rainbows that oil leaves on water.

One of the more colorful Turgite specimens that I have seen, this pleasant chunk of hydrated iron oxide not only has a generous rainbow-colored iridescent coating, it also shows a surprisingly large amount of botryoidal formation. These formations do not get very big(mostly 1/16" diameter nodules or smaller), but they cover an impressive percentage of the specimen's surface area. The piece's color spans the visible spectrum, and most of the iridescing areas have a submetallic to metallic luster. The areas without color also have a generous amount of this luster, which helps to emphasize the points where the iridescence begins. There is a whitish to colorless material that coats a part of the surface that I cannot identify that seems to be a bit weathered, but has a vitreous luster and no definite crystal form. Hmmm. Pretty rock, though.

This Hematite specimen occurs in the form of dozens of hexagonal platelets that are stacked together in a curving arc- the formation is called an iron rose. The platelets have excellent hexagonal shape and are damaged only at one end of the stack. They have the standard dark gray color, metallic luster, and opacity of Hematite on their basal faces, and their edges are a metallic red color. Two opposing sides of these edges are covered with clusters of tiny muscovite platelets. It is lovely to look upon!

Hundreds of tiny Hematite platelets are liberally sprinkled on one face of the host rock of this specimen. They occur in the form of misshapen tabular platelets that do not exceed 3 mm in diameter or 1 mm in thickness. As the platelets are so small and misshapen, it is difficult to determine the presence or extent of any damage to them; they do, however, have clean faces with no visible striations, so they sparkle rather brightly. The crystals have the standard dark gray color and metallic luster of Hematite. The larger crystals (those that exceed 1 mm in diameter) are concentrated into a thin encrustation on one face of the host, but hundreds more submicroscopic crystals are scattered elsewhere on the specimen. Examination of these crystals under magnification shows that many of them have very good hexagonal form. The host rock resembles some rhyolites that I have seen, but seems to be a bit soft- it may be a variety of shale.

This thumbnail specimen consists of a cluster of stacked hexagonal tabular crystals. I hesitate to call it an "iron rose", as the formation just doesn't bring that to mind. Some of the platelets are damaged and incomplete, but most are intact and show excellent form and a good hexaonal outline. They have the standard dark-gray coloration and a dull metallic luster along their edges, whereas their faces show a much brighter metallic shine. It is a pretty piece that I might just have to purchase for myself if nobody else does.

This small hand specimen consists of a portion of a botryoidal crust of Hematite that is often called kidney stone. It has a few interesting aspects to it. Most of its outer surface has a rather rough, pebbly texture that dulls its metallic luster. Only a small portion of this surface has a very smooth texture that enables one to see its metallic luster at its brightest. Examination of the crust's cross-section shows a distinctly radial pattern that suggests that the material had an almost fibrous habit at some point. Examination of its botryoidal surface, however, shows patterns that suggest concentric layering. After thinking about it, it would seem that the material DID form in a nearly acicular fashion, but was then partially covered over with smoother layers of Hematite. Examination of the specimen's underside shows a distinct lack of any host rock or material and the distinct red coloration of decayed Hematite.

This specimen is another example of the form of Hematite that is known as kidney stone. It consists of many intergrown nodules of Hematite that appear to have been polished to show better relief and detail. The nodules have the standard dark gray color and metallic luster of Hematite, and show hints of dull reddish color in the crevices where the nodules meet. A cross-section of the nodules shows their compact, radiating tendencies (see the close-up image). The entire specimen consists of Hematite, most of which is in a botryoidal form- there is no host rock of any kind present.

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.

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.

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.

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.

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

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.

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.

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.

Several small patches of crystalline Hematite are embedded in the rusty, rutile-laden base of this thumbnail piece. They are generally in very good condition, showing little damage, if any. The largest Hematite crystal has dimensions of 0.3 x 0.3 x 0.1" (8 x 7 x 3 mm) and shows definite evidence of its hexagonal tabular form, though its outline is jagged and uneven. Three rutile aggregates extend from it at 60-degree angles. The Hematite has the classic dark gray color and slightly dull metallic luster. The piece is affixed inside a plastic specimen box with an adhesive putty.

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.

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.

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.

Ouro Preto, Minas Gerais, Brazil
This is a cluster of hematite crystals intergrown in a form that is oft referred to as an "iron rose". This name comes from the resemblance of the crystals to the layering of rose petals in a bloom. These crystals are extremely lustrous, and are associated with tiny crystals of muscovite mica. On one side of the specimen the hematite crystals are stacked one atop another, this forms quita a thick "book" of crystals. This specimen shows only minor damage.

Heping, Guangdong, China
The pictures don't do this specimen justice - black on black just won't photograph well. A single nearly perfect quartz crystal rises from just above the center of a cluster of hematite roses, making a fairly striking presentation. The hematite is, of course, black and opaque, with the individual blades being generally well-formed. Many of the blades show minor damage, and there is a dusting of other minerals adding a gray or brown hue to the hematite from some viewpoints. There are actually quite a few smaller quartz crystals present, primarily on the back but also scattered on the front of the specimen. The smaller quartz crystals are technically citrine, as a thin outer layer has been stained yellow, predominantly towards the tips. That single large quartz crystal, on the other hand, is colorless except that exactly two of its faces have been roughened by inclusions of another mineral or two, almost with a sandpaper-like appearance.

Two large quartz crystals highlight the black hematite base of this specimen. THe hematite crystals are in fragile books of platy crytals which are very specular. Some of the hematite crystals (on the bottom) show yellow, blue, and red irridescence. Both quartz crystals also have a coating of hematite crystals on a couple of faces, and one crystal appears red from a coating on some of its faces.

Bouse, Arizona, USA
This specimen is nearly all hematite, and these crystals are very good. They are all flat hexagonal plates of black, opaque hematite. Some of them have an irridescent coating dominated by shades of blue and purple. The crystals tend to have a metallic to vitreous luster on the faces, and a dull luster on the six sides of the hexagon. There are other minerals present, including quartz and a crust of a dull green mineral that looks like a massive form of serpentine.
