Elegant is the best way I can describe this beauty. The elongated Acanthite crystals, up to about 3 cm in height, are lustrous, sharp, and well-formed. They have a flowing beauty all their own, and are accented by small, gemmy and frosted Calcites. One of the nicest specimens I have seen from Fresnillo in quite a while. It looks good from both sides!
Atacocha mine,Cerro de Pasco, Pasco department, Peru
Cabinet, 13.9 x 11.5 x 5.0 cm
From the mines of Peru we have a very good, representative combination piece. The matrix is predominantly intergrown, crystalline Tennantite, and it is draped with Sphalerites and decorative Manganoan Calcites. The Calcites themselves are adorned with hundreds of lustrous Pyrite pyritohedrons. The light pink Calcite crystals are about 2 mm in size and they number in the thousands as they cover half the specimen in ridges and mounds. Of course, the Manganoan Calcite has a rich orange-pink fluorescence. This cabinet specimen is in excellent condition, and the balance and aesthetics are very good.
Perfectly symmetrical pair of bladed Calcite spheres tinted a pretty grey color by inclusions of Boulangerite. They are 2.8 cm across, respectively, and the luster of the Calcite blades is very good. This is a near-floater, with only one small contact point. Choice for these particular combinations, this has very good, balanced aesthetics and visual appeal. From the 1990s.
CLASSIC Tsumeb style! The architecture on this cabinet piece is really quite alluring. Sitting on the Duftite-coated plate are actually FOUR clusters of classic, stacked Calcite rhombs. The rhombs are sharp, have good luster, and range from translucent to gemmy. The largest Calcite crystal is 3 cm on edge. Regrettably, there are a few visible dings on the crystals - a few on the faces and a few on the corners. However, the geometry and aesthetics here are so good and so unusual, if you can live with the dings, you get a noteworthy Tsumeb specimen.
N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa
Small Cabinet, 5.9 x 3.7 x 2.3 cm
Superb cluster of brilliant, Hausmannite tetragonal pyramids. The largest individual crystal is 1 cm and razor sharp, with the overall cluster being about 2 cm tall. The metallic luster is excellent, and the striations and complex growth are classic among the great Hausmannites. With this cluster resting perfectly right at the end of the Calcite matrix, the aesthetics are fabulous.
GORGEOUS and AESTHETIC, this gemmy, doubly-terminated and twinned Calcite crystal is from the famous Elmwood Mine. The rich amber color and gemmy terminations are exactly what you look for, and the condition is so good (just very minor edge wear and contacts) that it borders on pristine. There are minor amounts of Sphalerite and Barite, as well. A CLASSIC Elmwood Calcite crystal for form and color, and it even has a modest orange fluorescence as a bonus, which is unusual for the location. Although the mine is currently producing now, it is not giving up crystals of this combination of sharp shape combined with gemminess, color and luster - the new production is superb, but very different.
Brushy Creek Mine, Greeley, Viburnum Trend District, Reynolds Co., Missouri, USA
Large Cabinet, 22.2 x 15 x 7 cm
A large, spectacular, pristine cluster of grey Calcites from the well-known Brushy Creek Mine in Missouri. The condition is excellent, and sparkly Chalcopyrite and Marcasite has coated the recessed areas of the lustrous Calcites, making it exceptionally beautiful (what actually happened is that the original crystal was covered in Chalcopyrite, and then the Calcite began growing again, enveloping the original crystal in some areas and leaving the chalcopyrite exposed in others so this is actually a phantom). Really, the overall aesthetics are stunning and complex - more so in person as the sparkly nature of the coating does not convey well. These are from a major find in the early 1990s..
Pachapaqui District, Bolognesi Province, Ancash Department, Peru
Large Cabinet, 16.1 x 9 x 5 cm
Fine, highly representative combination piece from Peru, specifically the Pachapaqui District. The initial plate of lustrous, striated Pyrites was generously ringed by sharp, translucent to gemmy Sphalerite crystals (up to 1.9 cm), along with Galena cubes. The final generation is hundreds upon hundreds of 3-4 mm of complex, light pink Manganoan Calcite crystals. One side of the piece is completely covered, while the presentation side has the many Calcites placed decoratively on and around the sulfides. As expected, the Manganoan Calcites fluoresce a brilliant orange. There are a number of cleaves on the Sphalerites from contacting, but by their very nature they blend in well, and the overall good aesthetics of this piece are not really affected.
Hill-Ledford Mine, Ozark-Mahoning, Cave-in-Rock Dist., Illinois, USA
Cabinet, 11.0 x 10.9 x 4.6 cm
As with so many pieces in the Lillie collection, this one is unique! An intergrown, lustrous and translucent, lavender colored crystals of fluorite, to 1.2 cm across, host a few lustrous and translucent, straw colored calcite crystals to 5 cm across. The calcite crystal perched aesthetically on top of the fluorite crystals is twinned and complete all around !. A 9 mm galena crystal can be seen just to the left of the twinned calcite. Mined in the mid 1960's. Sering Collection. Former price $5500 on tag. RCL 1987.
Sub-Rosiclare Level Bahama Pod Denton Mine, Ozark-Mahoning, Harris Creek Dist., Illinois, USA
Cabinet, 11.7 x 11.2 x 7.3 cm
Nearly pristine, this large calcite crystal is glassy and translucent with a rich amber color. Most of the faces are smooth, but two clearly exhibit interesting and subtle stepped growth. This is a classic style rarely seen in such large, well-developed crystals in good condition and was mined in October 1992 from a single large pocket. It glows when backlit! RCL 1953.
Rosiclare Level, Denton Mine, Ozark-Mahoning Co., Illinois, USA
Large Cabinet, 18.8 x 14.0 x 11.0 cm
Really unusual specimen, unique in Ross's experience according to his own label: An earlier generation of fluorite and calcite forms the matrix for this specimen. Thin layers of lustrous, tan rhombohedral calcite then covered the original fluorite crystals. Aesthetically perched on all of this is a cluster of intergrown, lustrous and translucent, color zoned fluorite, in crystals to 4.8 cm across. The cores of the fluorite crystals are a dark amber, surrounded by a purple zone, then a dark purple rim and finally by a nearly colorless zone. Mined in April 1989 from the number four ore body. RCL 1843.
Hill-Ledford Mine, Ozark-Mahoning, Cave-in-Rock Dist., Illinois, USA
Large Cabinet, 22.2 x 19.6 x 11.5 cm
As with so many of the Lillie collection pieces, this is unique: Two, huge, lustrous and translucent, dark purple fluorite crystals, to 15 cm in length, are nearly covered in a druse of colorless calcite crystals. A few second generation, ivory colored, doubly terminated calcite crystals, to 1.5 cm in length, are perched on the druse. His label notes the unusual formation of parallel growth on the fluorites, stacked upon a dodecahedral core. The formation is highly unusual and very geometric, Although not gemmy, this piece has a form and presence to it, that is highly unusual. Mined circa mid-1960's. RCL 1318.
Bethel Level, Annabel Lee Mine, Ozark-Mahoning Co., Illinois, USA
Large Cabinet, 16.7 x 16.0 x 9.2 cm
A beautiful Illinois calcite that just sparkles in person! This is a solid mound of sparkling, translucent, rhombohedrons of rich amber colored calcite, to 2.6 cm across, is emplaced on shards of limestone. Mined August 1989 from the south end of the ore body near the top of the incline. RCL 1949.
Annabel Lee, Sub-Rosiclare Level, Harris Creek, Hardin Co., Illinois, USA
Cabinet, 10.5 x 7.9 x 6.2 cm
This amazing specimen is unique. It has incredibly gemmy, glassy, transparent crystals that are RAZOR SHARP, perched on a strange Baryte matrix. These are sharp, color zoned fluorite crystals to 3 cm across, which feature amber colored cores and light purple edges that are riveting in person - the human eye sees it better than a camera lens. On closer examination, the Baryte is casted after former calcites. From the Poe pod in 1993 and Lillie Collection, RCL #0458. Former dealer price was (no kidding) $20,000 when we purchased 1800 specimens from this collection and re-amortized pricing across the board. There is no question that it is a remarkable piece. It leaps out to the viewer, and is really "different" in aspect than all others here.
Rosiclare Level, Butterknife Pod, Denton Mine, Ozark-Mahoning, Harris Creek Dist., Illinois, USA
Small Cabinet, 8.5 x 8.3 x 6.1 cm
This really balanced and contrasting "combo specimen" features a doubly terminated, lustrous and translucent, amber colored calcite crystal, 7 cm in length which is perched on lustrous and translucent, color zoned fluorite crystals to 3.2 cm across. The fluorite crystals exhibit a light purple core and darker colored edges. It is starkly dramatic, 3-dimensional, and complete all around. Mined in 1987 from the Butterknife pod. RCL #0786.
Rosiclare Level, Denton Mine, Ozark-Mahoning Co., Harris Creek Dist., Illinois, USA
Large Cabinet, 16.2 x 9.7 x 9.4 cm
Perched aesthetically on St. Genevieve limestone are a few glassy and gemmy, amber colored calcite crystals, to 5.5 cm across. At least two of the crystals are doubly terminated. Mined in April 1985 from the main ore body. A nice piece for showing how these things form in the ground, amidst separated shards of matrix in pockets such as this. The calcites are unusually fat and translucent, well-isolated and dramatic. RCL 0779.
Sub-Rosiclare Level, Denton Mine, Ozark-Mahoning, Illinois, USA
Cabinet, 14.2 x 9.1 x 7.5 cm
A cluster of exceptionally lustrous and translucent, color zoned, light and dark purple fluorite crystals to 3 cm across is festooned with doubly-terminated, lustrous and translucent, amber colored calcite crystals to 1.8 cm in length. From the Bahama ore body in 1991. The fluorite crystals exhibit truly amazing luster and the camera cannot capture it except from the side angles. This is a dramatic combination piece with great contrasts, nearly complete all around except for only very minor dings. RCL 1758. Very nice combo specimen!
Okorusu is renowned for its multi-hued, attractive Fluorites, and I find it remarkable that a piece this good has become available. The crystals are sharp, a DEEP transparent purple/green, and multiply-phantomed. When backlit, this piece GLOWS with colors subtly changing from green to blue throughout, and you can clearly see that there are both cubic phantoms and fainter, thicker octahedral phantoms. Amazing! The luster is good, fluorescence excellent, and the largest crystal is an impressive 4.2 cm. There is also a coating of botryoidal, slightly fluorescent Calcite. You can display this fine Fluorite specimen from either side, depending on whether you prefer pure Fluorites or the combination, or rotate periodically. It is one of the better pieces from here that I have seen for sale in awhile, and is representative of older material from the 1`970s and early 1980s finds, as it last changed hands in 1994. Choice aesthetics.
Certainly, the famous Calcites with Copper are among the most coveted of all Michigan specimens. This thumbnail has so much going for it: color, rich inclusions, perfect shape, and luster. The Calcite itself is gemmy and doubly-terminated, and it is so rich with Copper that it takes on an unusually dark copper-red color hue, only rarely seen (I grew up near there and have seen only a handful of such "red calcites" in my life). This is really quite a choice specimen with excellent aesthetics. Overall, it must be the best such calcite thumbnail for my tastes, that I can recall. It has form, symmetry, color, luster, unusual qualities in the inclusions, and it just lights up in a display case like a little jewel.
A striking 3.8 cm GEMMY calcite with the most incredible superb luster, and great 'brightness.' What is so unique about this piece is the elongated habit and what appears to be Spinel twinning. The entire length is dominated by one single crystal. The calcites are really like glass, and I have not seen its equal for habit. These were from one special pocket in the mine in the late 1980s and have since been sold routinely as Moroccan anglesites when they turn up again on the market. This is only the second such piece that I have owned. It was sold to the former owner for $2000 as an anglesite. Top-notch Anglesites from the famous locality of Touissit are hard to find, and this calcite could pass! But it is, indeed, a calcite. The weight is wrong for anglesite, though it looks like it more than calcite.
A significant large calcite from the fluorite district: This huge, doubly-terminated, lustrous and translucent, rich amber colored calcite crystal measures in at a whopping 17 cm in length. Each termination is completely different from the other, which is highly unusual - most such cases show symmetry. The top termination as shown in the main photo I personally find the most attractive because of its stark simplicity with the simple rhombohedral termination atop the scalenohedral form. Others in the office like the complex termination, pointing up. You can choose, and we will make the base either way. It is perched on a sliver of matrix that includes as a nice accent a few galena crystals, to 1.5 cm across. There are also a few drusy, ruby jack sphalerite crystals and one small fluorite crystal under one corner of the calcite crystal. Cute associations! This piece was mined in May 1993. RCL 57
Just an impressive big matrix calcite of unusual aspect for this district. Aesthetically emplaced on a brecciated limestone and purple fluorite crystals is a large doubly-terminated calcite crystal cluster highlighted by small gemlike crystals to the sides. The calcite is lustrous and translucent with a rich amber color, and is 13 cm in length. There are a few insignificant bruises on the large calcite crystal which can be easily removed with acid if desired. Still and all, this is big, showy, and priced right, but it is nevertheless an major display piece for this district. RCL 1900
Bethel Level, Minerva Mine #1, Cave-in-Rock District, Illinois, USA
Large Cabinet, 28.7 x 11.8 x 9.7 cm
This huge, single scalenohedral calcite crystal is 5.5 pounds in weight! It is gorgeous: lustrous and translucent, along with exhibiting a superb, rich amber color. As the crystal grew it split into multiple terminations, almost 2/3 of which have pristine terminations (and the ones that have small cleavages at the tips get lost in the overall look anyhow). An amazing specimen! Lillie noted on the back of his label that this was one of the specimens selected by Chicago Field Museum in an attempt at a deal before he sold the collection, and that it is the largest good calcite of this style he has seen from the district. RCL 870
Rosiclare Level, South-End Main Orebody, Rosiclare Level, Denton Mine, Illinois, USA
Large Cabinet, 15.5 x 10.1 x 6.4 cm
Every now and then we get a surprise from these "fluorite mines," and that is what Lillie loved to add to his own collection. Here is a remarkable "combo specimen" that is just beautiful and complete all around, aside from anything else. It is an old piece from 1988, with purple fluorite crystals to 2.5 cm (showing beveled edges) across along with a splendent, battleship gray galena crystal (measuring 3.7 cm across), perched aside a stalactite of jet-black sphalerite crystals. Those are incredibly lustrous and to 1.5 cm across. In addition, a druse of nearly colorless calcite has formed in the interstitial spaces between sphalerite crystals. The calcite crystals glow a light tan color under fluorescent light. Lillie notes on his label that he thinks this is an example where "dissolution of spar results in shells or hollow casts of sphalerite/spar...excellent specimen." RCL 1010
Glassy and gemmy, light amber colored calcite crystals, to 1.5 cm across, totally cover a mound of cleaved, light blue fluorite. This is a choice piece of a rare calcite style showing complex growth faces and was considered highly desirable. In person, these are like little jewels. Mined in April 1995. RCL 599
Bethel Level, Minerva Mine #1, Cave-in-Rock District, Illinois, USA
Cabinet, 10.0 x 3.9 x 2.6 cm
An elegant scalenohedron of lustrous and translucent, amber colored calcite-or is it?! Look closely and you can see that the specimen exhibits two secondary calcite crystals at right angles to the main crystal - and those would be twins! Twinning is rare in Illinois calcite, and this particular habit ("butterfly twin"), even most so. Two twins in oriented growth on the same face of this large calcite are highly unusual. RCL 320
Rosiclare Level, South-End Main Orebody, Rosiclare Level, Denton Mine, Harris Creek District, Illinois, USA
Cabinet, 14.3 x 12.6 x 8.7 cm
A fine large Illinois specimen featuring a classic combination of species but with unusual size. Contrasting nicely with its corroded deep purple fluorite pedestal is a well formed, doubly terminated, glassy and translucent, rich amber-colored calcite scalenohedron. It is in remarkable condition given its huge size, measuring 14 cm in length. There are also present a few, tabular, white, barite crystals, to 1.3 cm across. Mined in 1981. No damage and complete all around, including the exposed termination! The piece shows nicely in a case, and the calcite glows when backlit. This is fairly important for the locality. RCL 868

Using the Search Form
All specimens for sale on the web site are entered into a
database. The search form allows you to specify criterea
to select the specimens you wish to view.
The form has a set of fields for you to fill in. You may fill in one
or more of the fields. If you fill in more than one, then only
specimens satisfying all fields will be returned. (Empty
fields match all specimens).
For the type-in text fields, the value you type in is matched
against the values in the field for each specimen in the database.
Since it's a pattern match, it's ok to type in partial
values. For example, when searching localities, if you simply
enter "China", you'll select all speciments from anywhere in
China. If you type in "Colorado, USA", you'll get all
specimens from the state of Colorado in the United States.
You can limit the search to specimens that were added during
some interval or prior to that interval. For example, selecting
"Before" and "10 Days" will search specimens added prior to the
last 10 days. Selecting "Since" and "10 Days" will search specimens
added during the last 10 days.
Each specimen has a unique alphanumeric ID, for example,
"CK42", or "URI-01". You can limit the search for specimens whose IDs contain a given
string of characters by specifying it here. You can indicate if
you would like "Partial Matches". For example "K-112" would match
"K-112" and "HECK-112". Or you can uncheck the "Partial Matches"
box to only retrieve exact matches.
Each specimen has a name field. Often the name is just the name
of the primary mineral(s) of the specimen. But in some cases,
there are conventions that can be useful in finding what you are
looking for. For example, all pseudomorph specimens will
the string "after" in their names, so you can find all pseudomorphs
by entering "after" in the Name field. Be aware that the name
field might include variety names ("amethyst", "aquamarine", etc.).
Thus, to be sure of finding all Beryl specimens, select Beryl in the
Mineral field - not in the Name field.
The Species field is different from the Name field, in that it searches
the list of species occurances noted for each specimen. (Not the
species names that happen to be in the specimen name!) It is more
precise than searching for species names in the Name field. For
example, if you search for just "A" in the Name field, you will find
Albites, Amazonites, Azurites, and so on... if you search for
specimens by specifying a Species in the Species
drop-down menu, the only specimens noting a occurance of that species
will be selected. The Species field allows IMA-approved species names,
only. (E.g., you'll find Quartz, but not Amethyst).
The locality field is populated with locality names. Spellings and the
locality hierarchy are generally as presented in the locality listings
Of course, you can also search by any part of the locality name,
for example, "Sweet Home Mine" would find all specimens from a
The Description field seaches in the specimen descriptions.
Since previous owners are usually named in the description,
you can search for "Arthur Montgomery" to look for specimens
sold by the noted American mineralogist (or perhaps even from
Montgomery's personal collection).
Allows you to search based on the specimen sizes.
By filling in these fields, you can limit the search to a particular
price range. For example, with "Min Price" 1000 and "Max Price" of 2000,
the search will only match specimens in this price range.
Allows you to constrain the search to specimens formerly in the collection
