Lei Yang, Hunan Province, China

There are six visible cubic Fluorite crystals on this specimen. Five of them are tightly intergrown into a cluster, and one is separated. They are in good condition, and the damage that they have appears to have occurred prior to the specimen's separation from its place of origin. The largest of these cubes is part of the intergrown cluster and measures 0.8 x 0.8 x 0.7" (2.1 x 2.0 x 1.8 cm). All are colorless, and though some appear to have a slight tinge of violet, I think that it emanates from one small area that I cannot pinpoint. The crystals luster changes according to the directions that in which their faces point. Some of the faces that point in a general direction have a more pearly luster, and seem to "sparkle". Other faces that point in a different direction have a bright, vitreous luster, enabling one to take advantage of the crystals' transparence and clarity. All show substantial internal fracturing and cleavage planing, though. They rest on a base that is made up of countless white, intergrown dolomite crystals that have a bladed, prismatic form with curved faces and a dull, waxy luster.

Lei Yang, Hunan Province, China

A large and superb specimen, this piece contains over 100 cubic Fluorite crystals, as well as crystals of several other minerals. It is in good condition, with moderate damage in general. The Fluorites range in size from a few millimeters to 0.4" (1.0 cm) in all dimensions, and have excellent form with well-defined edges and clean faces that give them a vitreous luster. All are colored a pale blue with a hint of violet, and are clean and very clear with few internal fractures and flaws. There is one small isolated cluster of Fluorites on the specimen wherein the crystals contain faint, milky phantom inclusions that lay about 1 mm below their surfaces. Another small patch of isolated crystals have a rather intense violet color, but these are tiny and not as well-formed. Among the Fluorites lay countless tiny quartz crystals that are colorless and nearly transparent, along with as many small rhombohedral calcite and/or dolomite crystals that have a cream color and are opaque. There are also several cubic pyrite crystals that are intergrown into a vein that runs through one end of the specimen. Most are broken, and only a few are undamaged. They have the standard pale gold coloration and metallic luster of pyrite. This is what I think of when somebody says a "cabinet specimen".

sub-Rosiclare Level, Hill & Ledford Mine, Ozark-Mahoning County, Illinois, U.S.A.

Seven or eight intergrown cubic Fluorite crystals make up the bulk of this specimen. Whether due to intergrowth or the small amount of breakage on the specimen, none of the crystals are complete. However, they all show excellent cubic form, with well-defined edges and clean, smooth faces that show a dull, vitreous-to-pearly luster. The largest of these cubes measures 2.0 x 1.9 x 1.4" (5.1 x 4.8 x 3.6 cm) and is probably the least complete of the cluster, though it shows almost no human-induced damage. The other crystals are much smaller than this, and do not exceed 0.7" (1.8 cm) in any dimension. As with the other crystals, it is transparent and quite clear, enabling one to see a few subtle phantoms within when examining it under bright light. Deep within the crystal is another, much smaller included Fluorite cube- part of it is protruding from the "incomplete" surface of the crystal. This cube is quite visible through the surface of the larger one, which, incidentally, has a pale blue color with some patches that have a subtle violet shade. Attached to the Fluorites is a cluster that is made up of at least 10 intergrown calcite crystals. They have the form of "composite crystals" that each appear to be made up of many smaller crystals that are aligned with each other and heavily intergrown. It is a very beautiful specimen.

Clay Center, Ohio, U.S.A.

This small hand specimen consists of a calcareous shale base on which rest at least 20 cubic Fluorite crystals. Almost all of them are in excellent condition, having little damage and excellent form, with well-defined edges and clean, smooth faces that have a vitreous luster. They have a faint yellow coloration and are transparent and very clear. They do not exceed 0.3" (8 mm) in all dimensions, though one crystal in particular has dimensions of 0.5 x 0.2 x 0.2" (1.3 x 0.5 x 0.5 cm). Among the Fluorites are several thin blades of celestite that show considerable damage. All are colorless, transparent and clear, with a vitreous luster. There are also scores of tiny, cream-colored scalenohedral calcite crystals that do not exceed 1 or 2 mm in length. They have a dull luster and are translucent at best. These crystals were found in a 600-foot-deep pocket in the Silica Shale formation. They accompanied a fossil find that dates back to the Ordovician period.

Naica, Chihuahua, Mexico

A very simple thumbnail specimen, this piece consists of two separate and distinct clusters of Fluorite crystals resting on a crystalline sphalerite base. The larger cluster measures approximately 1.0 x 0.9 x 0.8" (2.5 x 2.3 x 2.0 cm), and the smaller has dimensions of 0.6 x 0.4 x 0.4" (1.5 x 1.0 x 1.0 cm). Each Fluorite cluster appears to be composed of many intergrown cubic crystals that are all aligned with each other. The largest of these crystals measures about 0.3" (8 mm) across its only completely visible face. All are colorless, reasonably clear, and have a vitreous luster on their faces. All of the visible edges of all the crystals in both clusters are truncated by secondary faces. Upon close examination of the largest crystal face in the larger cluster, I noticed that there are fibrous, needle-like crystals visible below the surface. Further examination showed that such crystals are visible in a few other places on the cluster- I do not know their composition. The sphalerite base on which the clusters rest appears to be made up of several incomplete and intergrown tetrahedral crystals that have the standard dark brown color, opacity, and adamantine-to-metallic luster.

Elmwood Mine, Carthage, Smith County, Tennessee, U.S.A.

The largest specimen in our present stock, this cabinet specimen consists of four large, intersecting, cubic Fluorite crystals. Though none of the crystals are more than 50% complete, it appears that the specimen was broken off of its host during its formation, as both breakage surfaces show partial healing and almost no human-induced damage. The largest of these crystals measures 5 - 5.5" (12.7 - 14.0 cm) and its one nearly complete face is covered with smaller cubic crystal projections. Each crystal has a deep violet coloration and a pearly-to-waxy luster that is caused by countless tiny cubic prokjections that slightly break the continuity of their faces. Ther edges are well-defined. The specimen is completely translucent under a bright light, showing its beautiful color. Besides the Fluorite are a few clusters that are made up of dozens of intergrown sphalerite crystals. These crystals have the standard steep tetrahedral shape of sphalerite, but are somewhat warped due to their heavy intergrowth. They have a dark brown coloration and an almost metallic, adamantine luster. The crystals are in good condition, showing little damage, and are only dimly and partially translucent in very bright light. It is one of the largest Elmwood Fluorites that I have been able to examine closely.

Moscona Mine, Asturias, Spain

The most noticeable aspect of this specimen is its unusual golden coloration. It consists of a cluster of dozens of cubic crystals that show almost no damage whatsoever and are rarely more than 50% complete due to their heavy intergrowth. The largest of these crystals measures nearly 0.5" (1.2 cm) along an edge, and like the others, has excellent form with well-defined edges and clean faces that show a slightly dulled vitreous luster. The crystals are all transparent and moderately clear, though they each show some cloudy inclusions. There are many very small, white dolomite crystals growing mainly on one side of the cluster. These are likewise in excellent condition, and have the curved, bladed form that is common for that mineral.

Moscona Mine, Asturias, Spain

A very atteractive specimen, this piece consists of dozens of golden Fluorite crystals whose combined formation has an almost stalactitic appearance. All are in excellent condition, as only a few spots of minor damage are visible. The crystals measure a maximum of 0.4" (1.0 cm) along an edge, have the classic cubic form, and are heavily intergrown. They have well-defined edges and smooth faces that show a bright, vitreous luster. Their color is a rather unusual golden tint and they are transparent and very clear, so that one can see several rusty inclusions that are scattered within. There are a few small patches of colorful chalcopyrite and several small, white dolomite rhombohedrons (most of which are damaged) scattered on the specimen, and only a very small amount of a brown host rock.

Denton Mine, Cave-In-Rock, Illinois, U.S.A.

This hand specimen consists of a cluster of several cubic Fluorite crystals- I count at least 20 different crystals, though many of these are mostly incomplete. They are generally in very good condition, showing a few scars along the corners of one or two cubes and the inevitable damage from the piece's separation from its place of formation. The largest of these cubes has visible dimensions of 1.4 x 1.0 x 1.0" (3.6 x 2.5 x 2.5 cm) and like the others, is incomplete due to heavy intergrowth. As seen in the close-up image, these crystals have formed in such a way that their edges continued to grow for a while after their faces stopped. Thus, some of the crystals show a partially complete "crust" of violet Fluorite over a dull-golden "core". Both the core and crust are transparent and quite clear, and have a pearly-to-waxy luster. Off of the center of the cluster is an outcropping of sphalerite. It has a black color with brown highlights and a bright, vitreous luster, and is opaque. There is a thin layer of calcareous shale or mudstone host rock on the specimen's underside.

Denton Mine, Cave-In-Rock, Illinois, U.S.A.

This is one of the most unusual specimens I have seen come from the Cave-In-Rock locality. It consists of a cluster of cubic Fluorite that partially grows over a large, crystalline formation of sphalerite. The Fluorites have a pale violet coloration and a rather dull, waxy luster, and are transparent and clear, though the dull luster provides some interference. The largest of these crystals have dimensions that slightly exceed 1" (2.5 cm). The sphalerites seem to consist of countless tiny crystals that do not exceed 2 mm in any dimension. However, they are all aligned with each other so as to appear to form two large, intergrown crystals. Both the Fluorite and sphalerite are pervaded with many tiny but well-formed chalcopyrite crystals. These are visible both on the sphaerite's surface and trapped just under the surfaces of the Fluorites. They are not visible beneathe all of the faces, though. There is a small amount of a pale brown, sandy host rock on the specimen's underside.

Elmwood Mine, Carthage, Smith County, Tennessee, U.S.A.

This hand specimen consists of 3 intergrown and incomplete Fluorite cubes. Two of these are more than 70% incomplete, but the third is at least 50% complete and has dimensions of 2.0 x 1.9 x 1.4" (5.0 x 4.9 x 3.6 cm). It is visibly damaged, but this damage is concentrated around its base, where it was broken off of the base on which it grew. Its cubic form is excellent, with relatively well-defined edges and intensely patterned but clean faces. It has a rather deep violet color and a greasy luster and is dimly transparent due to internral fractures. A small amount of sphalerite is attached to its base, but no limestone host material is present.

Like the previous specimen, this piece consists of a crust of intergrown calcite crystals that is the matrix for scores of tiny Fluorite cubes. These cubes do not exceed 0.1" (3 mm) along an edge- most are considerably smaller than that. Most of the exposed crystals are damaged, but not very many of them are exposed. The rest are intact and in good condition, showing a somewhat warped cubic form. However, all appear to be rather heavily intergrown and possibly trapped in a matrix of colorless, transparent calcite. These rest on a layer of what might be natrolite, as the short, radiating crystals are fine and fibrous. All of this rests on a thin, rough brown crust that I cannot quite identify. This piece and the others like it in our selection are quite mysterious.

At least 20 heavily intergrown Fluorite cubes rest on the dark gray host rock of this specimen. These cubes show slight damage and achieve diameters of 1.2" (3.0 cm). All have a rather unusual cubic form, in that their faces are heavily patterned and did not grow quite as quickly as their corners, which are truncated with large, clean secondary faces. Their edges are not well-defined, and are truncated by small tertiary faces that are stepped and uneven. All have the pale green color that is standard for Fluorite from this locality and a pearly luster. They are transparent and appear to be quite clear, though their pebbled faces prevent a clear view within. Together they form a crust that coats most of the surface of the black host rock.

Xianghualin, Hunan Province, China

One of the more unusual Fluorite pieces I have seen lately, this large cabinet specimen consists of a large, possibly stalactitic formation of intergrown Fluorite cubes that are coated with a thin druse of tiny, white quartz crystals. The quartz crust is made up of thousands of tiny hexagonal prisms and is no more than 0.2" (5 mm) thick. However, it almost completely covers the Fluorites, except for where the piece was separated from its place of formation. Therefore, the Fluorite crystals are obviously almost impossible to study, but one can see from the breakage area at the base of the specimen that they have a pale green coloration, and one can still see their cubo-octahedral form, which appears to be quite good. The formation acts as a base, though, for 20 to 30 smaller Fluorite cubes that grew at a later time.

This large hand specimen consists of several intergrown Fluorite cubes. These cubes range in diameter from a few millimeters to 2.2" (5.6 cm), and are in moderately good condition, as there are a few areas of obvious damage on the piece. Though none are complete, the crystals have excellent cubic crystal form, with well-defined edges and faces that are composed of many smaller, individual faces that possess a very bright pearly luster. Their dark violet color seems to be concentrated at the surface of each crystal, and fades rapidly about 0.3" (8 mm) down. Though it is almost impossible to determine, I believe that their interior material is transparent and reasonably clear, though it does contain a few internal fractures. There is no host rock or other material present.

All have a pale green color which is common for material from this locality and a bright, nearly vitreous luster. They are transparent and quite clear, though they do contain many internal fractures. The quartz druse that covers the Fluorites is made up of scores of intergrown quartz crystals that do not exceed 0.1" (3 mm) in length. All have good form and an impressively bright, white coloration.

All have excellent cubic form, though most have truncated edges, and the larger ones are nearly cubo-octahedral. Their edges are very well-defined, and their faces are clean, possessing a bright, vitreous luster. All are colorless, transparent, and moderately to very clear. They are accompanied by one large, white partial calcite crystal and several small, white quartz prisms.

This hand specimen consists primarily of a small formation of crystalline Fluorite. The formation shows no definite form of its own, but is made up of scores of heavily-intergrown Fluorite cubes. These cubes are generally in good condition and reach diameters of nearly 0.4" (1.0 cm). Their cubic form is excellent- all edges are very straight and well-defined, and all faces are extremely clean- and are slightly unusual in the fact that each edge is truncated with a thin secondary face. All are colorless, transparent, and impressively clear, though their intergrowth tends to interfere with the view to their interiors. Clusters of white calcite or dolomite rest on the Fluorite, and these serve as a base for several small chalcopyrite crystals. A small amount of broken sphalerite and galena is left from its base material.

A few intergrown, partial Fluorite cubes make up this small hand specimen. They measure up to 1.5" (3.8 cm) along an edge and are in very good condition, showing little damage. Their cubic form is also very good, and all have a violet-and-pale-yellow coloration that caused by phantom layering within each crystal. Their luster is greasy and all are transparent and dimly clear. Several tiny pyrite or chalcopyrite crystals are partly embedded in the natural surfaces of each crystal, and a few have been included. There is no host rock present.

Nancy Hanks Claim, Colorado, U.S.A.

This piece consists of a Fluorite crust that partly coats a brown quartzite or sandstone base. The crust is made up of countless small Fluorite octahedrons that are extremely intergrown. It is in good condition, but one can only just discern the crystals therein. They have a pale green color and a greasy luster and are translucent. Many tiny quartz crystals rest on this crust- they do not exceed 0.1" (3 mm) in length and show good hexagonal form.

It has excellent cubic form, with the pebbly, patterned surfaces that are common for crystals from this locality. One can see that this pebbly surface interferes with the view into the otherwise transparent and very clear crystal and gives it a dull, waxy luster. Its moderately pale purple color is likewise mostly caused by its surface, which has a dark violet color in a thin layer. It is rests on a druse of countless tiny calcite crystals and is accompanied by scores of tiny, white dolomites.

Its cubic form is very good, and though at least 4 of its corners seem to be cleaved off, these truncations are actually natural- one can see the crystalline patterns on their surfaces through a 10-power loupe. The smaller crystals are generally less than half the size of the larger and are in good condition, showing a paler green color than the large crystal. All are transparent and moderately to very clear, and have a dull pearly to waxy luster by which one can see a subtle patterning on their surfaces. I am not sure what the base rock is, but the piece is easily mostly Fluorite by weight. This specimen presents very well as a single green fluorite cube.

All have excellent cubic form and heavily patterned surfaces and the common deep violet color. Their luster is greasy to waxy and their color is so deep as to render them only dimly translucent. The sphalerite crust shows damage in several areas but is generally in very good condition. All are heavily warped due to twinning and intergrowth, and all have the classic deep brown color and adamantine luster.

A chunk of rock was cut and broken open to reveal two cavities. These are lined with fluorite crystals in three layers. The outer layer consists of pale brown crystals whose terminations are completely hidden by the upper layers. This layer fluoresces very bright yellow under long wave UV, and white under short-wave UV. The next layer is of small, transparent, brown fluorite cubes, which do a good job of blocking the UV from the underlying fluorite - the result is a bright "ring around the cavity". Finally, there is a number of excellent purple fluorite cubes, including one crystal measuring 7mm on the longest side. The purple on brown has a pleasing appearance, almost like an irridescence, as you examine the crystal.

This is a typical Auglaize Quarry fluorite. It has three layers of fluorite lining a cavity in the host rock. The first layer is pale brown, fluoresces bright yellow under LW UV, bright white under SW UV, and is only visible around the edges, as it has been completely covered by the other layers of fluorite. The second layer is pretty brown cubes which almost look like they have a coating of gold. And scattered about on top are numerous purple fluorite cubes, whose color (when examined with a loupe) is concentrated in an outer layer (about 0.2mm) of intense coloration, and a few of the cubes are missing that outer color layer and appear completely colorless.

The fluorite is very pale blue and highly transparent, with a vitreous luster. Some of the crystals have deep violet color splotches as inclusions, but what I find most interesting is that nearly all of the crystals have one or two thin violet color zones about 0.9mm below the surface and less than 0.1mm thick. These color zones give the visual appearance of an outline around each crystal. There is relatively little damage to the points and edges of this delicate mineral, although towards one end a point has been cleaved off and there is an area with a fairly smooth, curved fracture surface.

A polycrystalline rock is host to a dozen or so cubes of fluorite. These are transparent and yellow, although they are so pale as to be nearly colorless. They all have a few internal fractures, and some hints of a milky veil inclusion. The crystals that are most exposed do show minor damage to edges and corners. The host rock is based upon a finely granular crystal mass which sparkles nicely and may be quartz, but even a loupe does not show individual crystals. On this are hundreds of colorless rhombic crystals of calcite, and thousands of tiny flat colorless trapezoidal crystals that look like barite (or celestite or a similar mineral). Under long wave ultraviolet, the fluorite glows a bright yellow (especially those milky veils), and under short-wave it glows a dim yellow.

A single, large octahedral crystal of fluorite adorns this specimen. It is slightly distorted, as two faces are longer than the other two, and instead of a point, the termination is a short ridge, and the bottom 4 sides are buried or missing. The surface texture is very rough, so it is difficult to be certain, but I believe that the fluorite is transparent. Held under a bright light, there are indications of colorless areas deep within the crystal, and the dark host rock may also be visible, while the fluorite appears a pale green over-all. The host rock is a black mineral (opaque and vitreous), with no crystals to assist in identification, and it contains inclusions and a coating of transparent fluorite, followed by a layer of translucent white crystals that look like quartz, and these in turn are partially covered with yellow dimly transparent crystals that look like sphene (but of course they may be something else, perhaps even one of the hundred habits of calcite).

A brown host rock is partially covered with hundreds of cubic fluorite crystals, a few of which are relatively large, and the largest exceeds 12mm on a side. Most are relatively uninteresting, with only a slight green color, but all glow brightly under long wave UV light. Their fluorescence is a bright blue or purple-white, probably several colors combined to make this one hard to describe. These green fluorites from the Rogerley Mine have another interesting characteristic - they look a pale green under incandescent light, and some areas look violet under sunlight.

Xianghua Lin, Hunan Provence, China

This is a pretty and unusual fluorite specimen from China. It is almost entirely fluorite, although there is a small amount of the quartz host rock exposed on one end of the specimen. The color is a slightly bluish-green (some might call it a "sea foam green"), with the color concentrated towards the base. If you hold it up to the light, the tips appear nearly colorless. What makes it unusual is the shape of the crystals. They are basically octahedrons whose sides are very bumpy, almost giving them a rounded appearance, and all appear (at first glance) to have their tops cleaved off. However, close examination reveals that these flat tops are really growth patterns similar to little drops of paint spattered on a flat surface. The "bumps" all over the sides look like rounded cubes, and if they were regularly spaced instead of random, the net effect would be more like a miniature pyramid built from stone blocks.

Xianghualin mine, Hunan Province, China

There are a number of fluorite cubes on this quartz host rock. The largest crystals are a pale green in color, and the numerous small fluorite crystals are a pale sky-blue. All are cubs, and especially the largest ones are in excellent condition, showing no damage. The quartz crystals are prismatic and basically colorless, although they have a rough exterior lending a milky appearance, plus many dark inclusions giving them a nearly smoky quartz appearance.

Ost-Sibirien, Dalnegorsk, Russia

A large green fluorite crystalis nicely perched on a black host rock. The fluorite is transparent a a pale lime-green in color, but shows no crystal form. Also, its surface is quite rough giving it a dull appearance. The host rock is mostly composed of quartz, and the surface is largely covered by thin, empty shells of (probably) milky quartz. Apparently, all of this was embedded within (and intergrown with) some other mineral, likely calcite, which has been etched away, exposing the fluorite. There are actually quite a few small crystals of fluorite, some of which are tiny cubes.

This is not a very pretty fluorite specimen. While the crystals are transparent and have a rather unique green color with the slightest hint of blue, they have a moderate amount of damage and internal fractures causing an often milky appearance, plus the underlying matrix is mottled gray. Several of the fluorite crystals have a coating of this gray mineral, which I believe to be a dirty quartz crystal druze. Under long-wave ultraviolet, the specimen comes to life with a bright blue fluorescence typical of Rogerly fluorites.

Xianghua Lin, Hunan Provence, China

The surface of this specimen is dominated by pale green crystals of fluorite. They are heavily intergrown and have a rounded appearance. The many flat surfaces are likely cleavage planes, although many of them have quartz crystals on top indicating that if they did cleave, it was not man made damage. There are so many quartz crystals that the specimen has a frosted appearance. There are also clear colorless blades that look like barite. All of this is perched upon a large piece of sphalerite which itself is transparent (!) and green in some places, yellow in others. Were it not for the heavy covering of fluorite, this might have made a very appealing sphalerite specimen, as transparent sphalerite is quite uncommon.

Several intergrown crystals of fluorite are set upon a bit of black host rock. The fluorite is a pretty shade of green, and it is transparent although that is difficult to see since the surface has a rough texture giving the fluorite a very dull (or soft) appearance.

Dalnyegorsk, Russia

This unusual specimen consists of a base of intergrwon thin plates, allof which are coated with flower-like clusters of tiny rounded white quartz crystals, and upon this perch several intergrown crystals of transparent green fluorite. The fluorite crystals are generally incomplete octahedrons, yet the overall appearance is of a rounded mass. The fluorite fluoresces a pale blue under long wave ultraviolet.
