Cavradi gorge, Curnera Valley, Tujetsch, Vorderrhein Valley, Grischun, Switzerland
Cabinet, 10.0 x 8.0 x 8.0 cm
Cavradi hematites are iconic in the mineral world, and not just only Swiss classics. Nothing else looks like these, from anywhere... These sharp hematites generally have the finest luster and sharpest form, but it is the association with clear gemmy quartzes that makes them rise to the top of collector desirability in Europe and overseas. This particular specimen has all of those attributes, and i... Read more
This is a dramatic, arborescent specimen that shows the classic qualities of a finely filigreed crystallized gold from this mine, where it looks like a tree standing on white rock. The piece is sturdy, not fragile at all, and presents in a very balanced way with excellent aesthetics. It is good on either side, front and back. This large specimen is without the repairs or soldering that can sometim... Read more
Dos Cabezas placers, Dos Cabezas Mts, Cochise Co., Arizona, USA
Small Cabinet, 8.3 x 5.0 x 4.0 cm
This is a hefty and aesthetic nugget from the famous Dos Cabezas placer deposit, that is unusual for its beauty and richness for this locality. At 379 grams including the quartz, it probably contains about 10 ounces of total gold by weight (though we have not done a SG test on it). The value, in any case, is how nicely it displays as an Arizona gold in a case, whereas most are flattish lumps! Rare... Read more
The Sapo Mine blue caps of the late 1990s really shocked us when they came out for the beautiful color pattern and intense blue tops with luster not seen since a very few specimens came out of San Diego in 1972. They literally evaporated from the market at that time. I had this piece then, around 1998 or so, when I bought it as a big clunker after it was mined. I trimmed it down to size and sold i...

Electric Meatball Mine, La Paz County, Arizona, USA
Small Cabinet, 7.5 x 5.4 x 2.0 cm
A rare museum-sized, large display specimen of sharp zunyite crystals from a single find. This is truly an amazingly rich specimen of zunyite from the location which produced the world's best of species crystals! Vitreous, slightly translucent, sharply tetrahedral crystals 1mm on edge present as gray-blue crystals on the contrasting matrix. These are large, lustrous, exceptional crystals for the s...

Bishop Mine, Lynch Station, Campbell Co., Virginia, USA
Miniature, 5.3 x 5.2 x 2.7 cm
A beautiful blue specimen of Turquoise, but actually crystallized instead of a nugget! Crystallized turquoise is for some reason a true rarity in nature and occurs only at a very few localities worldwide. This one, in Virginia, is the most famous of them. While the crystals individually are sub-mm, this piece overall has an incredibly rich and pristine coverage area that is loaded with them, makin... Read more
Greek rhodochrosite is uncommon, and especially with "sparkle" as it tends to be dull in luster. Here we have the solution - Beautifully formed rhombohedrons of light pink rhodochrosite to 3 cm across are partially covered by a secondary, drusy layer of sparkling, colorless quartz. This is a example of uncommon, aesthetic rhodochrosite from Greece! The large rhodochrosites formed as pseudomorphs a... Read more
Goosecreekite is one of those species often overlooked in the flood of other, more common, Indian minerals. However, they are by 100 times, the world's best! While available each year in a few decent specimens, we are talking about 1 out of thousands of pockets, that has good material in it. This particular specimen came from a pocket in 2015 that has produced some of the brightest, snowy-white, s... Read more
Mundo Nuevo Mine, Huamachuco, La Libertad Dept., Peru
Thumbnail, 2.8 x 2.1 x 1.3 cm
This fine, small cluster of glassy and gemmy, light green, augelite crystals, to 1.8 cm in length, is perched on a bit of matrix. Arguably the best augelites in the world, small pockets of these from this long-known mine for hubnerite and quartz, and pyrite, have continued to amaze collectors. The big finds seem to be over, with the best veins found 2012-2013 and now only a trickle of lesser speci... Read more
A dramatic and very sculptural, huge schorl, complete all around, balanced by a naturally attached pedestal of quartz! This is from the Skardu road pegmatites (that are admittedly much more famous for smaller tourmalines, and tourmalines of color, making this a highly unusual locality piece as well). The quartz grew emplaced on and partially in a glassy and gemmy, colorless quartz crystal measurin... Read more
Miguel Vaca Mine, Pardais, Evora District, Portugal
Small Cabinet, 5.6 x 3.1 x 1.3 cm
A rarity for the Portuguese locality, AND superb crystals of the species as well - these are significant libethenite crystals. Nicely emplaced on sparkling, drusy, white quartz are lustrous, green-black crystals, to 7 mm across, of libethenite, a less common member of the olivenite group. Ex Bill Pinch collection (sold in 2002).
Sphalerite is one of the few sulfide ore minerals that can be gemmy enough to be cut into gemstones. This one could be! The colors range from red to orange to yellow. This particular sphalerite specimen on white quartz features two glassy and gemmy, orangey-yellow crystals, to 2 cm across. Just beautiful!
A rare Faden Quartz, from a single famous find in France of the early 2000's, I got this long ago by exchange from the Benjamins and sold it (and got it back recently). This elegant cluster is composed of flattened, doubly terminated, parallel growth of glassy and gemmy, colorless quartz crystals to 2 cm in length. Note the faden lines inside, which show as a distinct white band or thread through ... Read more
Perched aesthetically high atop a massive quartz matrix is doubly terminated, glassy and gemmy, yellow londonite crystal measuring 1.6 cm across. It is associated with a smoky quartz crystal measuring 2.4 cm in length along with shards of rich pink tourmaline (Liddicoatite). Londonite, first discovered and named after our friend Dr. Dave London at the beginning of this century, is the cesium domin... Read more
Sunshine #8 Claim, Bradshaw Mts, Yavapai Co., Arizona, USA
Thumbnail, 2.2 x 2.0 x 1.1 cm
Arizona golds are rarely seen for sale! This is such a rare locality gold specimen, this cute thumbnail piece shows a nice patina and microcrystalline structure which would be considered actually quite nice for this locality. I obtained it over a decade ago in a trade from well-known Arizona collector, Les Presmyk. 8.5 grams.
This rare locality piece features dramatic, thick, pointedly elongated gold crystals mixed with leafy gold, on quartz matrix. The piece looks good all around, 360 degrees, and displays well from any side. It masses 86 grams. Purchased from one of the well known gold dealers at Quartzite in the late 1990s, this was marked $12,500 even at that time but came to us in a large collection and can be sol... Read more
This rare locality piece is a characteristic style found twice: in the 1880s and later in one pocket in the early 1990s. It is from a single famous pocket which produced some of the finest golds seen since the gold rush era, in a lucky find by metal detector on long-worked property. The vertical flame of gold is 3.5 cm tall. The pieces from this find are in major museums and collections around the... Read more
A hefty, half-ounce specimen of intergrown "wire gold" and quartz matrix, from the classic finds here of the late 1990s. Very sturdy, and now hard to come by today. 15 grams. The piece is 360 degrees, complete all around.
A particularly elegant example of a species which is seldom "elegant" in specimen form; highly lustrous, dark gray, fan shaped, crystal clusters of semseyite, an uncommon lead antimony sulfosalt, exhibit rows of parallel growth on a natural pedestal of matrix composed of other species. Closely associated with the semseyite are two milky quartz crystals, to 1.2 cm in length. Accents are a bonus her... Read more
Spruce Claim pyrites are considered by many to be the finest in the USA and contenders, at their best, for worldwide status due to the combination with quartz and brilliant pyrite luster combined with sharp form. Nestled beautifully among glassy and gemmy, colorless quartz crystals, to 4 cm in length, are two pristine, well formed, splendent, brassy yellow crystals of pyrite to 3.3 cm across. With... Read more
Native bismuth seldom crystallizes so richly as you have here; an almost 2cm-thick seam of native bismuth crystals is layered between crude quartz "vein boundaries" within this natural matrix piece, which shows clearly how the bismuth crystallized to fill a thin fracture filling as it formed out of solution tens of millions of years ago (or more). The bismuth crystals exhibit metallic luster and d... Read more
Ace of Diamonds Mine, Middleville, Herkimer County, New York, USA
Small Cabinet, 6.2 x 3.6 x 3.0 cm
Perched aesthetically on a sliver of dolomite which is impregnated with 'anthraxolite' (a pyrobitumen), are three superbly formed, glassy and gemmy, colorless quartz crystals to 3.8 cm across. This style of New York quartz crystals is nicknamed with worldwide fame as "Herkimer diamonds." This piece is actually a superb cluster for the size range, with brightness and excellent condition. Unlike mos... Read more
Butte is a highly collectible locality, which has produced some of the world's finest covellite specimens (primarily in the 1960s and before). While many collectors now own a great Butte covellite, I think nobody has a combination specimen like this! An unusual combo specimen, this piece features tabular covellite crystals, to 2.5 cm on an edge, that have been altered into the more robust copper s... Read more
Old English brookites are exceedingly rare, and this is a textbook example! A single, highly lustrous and glassy, rich brown colored brookite crystal, 1.4 cm across, is emplaced on a drusy quartz on a limestone matrix. It is assumed by us that the crystal has been repaired to its matrix at some time in the past, judging by a hairline crack in part of the crystal and some faint yellow fluorescence ... Read more
Siglo XX Mine, Llallagua, Bustillo Province, Potosi Department, Bolivia
Small Cabinet, 7.9 x 5.0 x 4.3 cm
Arsenopyrite seldom crystallizes with such equant, fat 3-dimensional crystals! Since arsenopyrite is not so common from Bolivia, we do not expect anything "great" to come out of there, of all places in the world, for this species. Yet, this piece really stands out; a cluster of large, well formed, highly lustrous, silver-colored arsenopyrite crystals, to 5.2 cm in length, is associated with minor ... Read more
Aesthetically perched high atop a matrix of lustrous and translucent, colorless, stubby quartz crystals, to 1.7 cm in length, are two VERY sharp octohedrons of lustrous and translucent, rich emerald green fluorite to 2.4 cm on an edge. The fluorite crystals intersect each other but do not appear to be twinned. The sharp perch and extreme gemminess of these crystals makes this piece a higher level ... Read more
A highly sculptural specimen in 3-D; an undulating layer of small fluorite crystals culminates in a lustrous and translucent, rich emerald green, fluorite octahedron, measuring 3 cm on an edge and 4 cm across the tips. The large crystal is partially encased by a druse of darker quartz alternating with whiter quartz, for contrast. Like others in this lot, it is unique in some way, even amongst many... Read more
A gem cluster with extraordinary clarity and gemminess! Emplaced on a matrix of colorless quartz is a cluster of lustrous /translucent, rich emerald green, fluorite octahedrons. The largest crystal, perched nicely in the center, measures 3.1 cm across. The crystals are a rich purple under fluorescent light.
Wreathed by drusy, colorless quartz, and tiny crystals of what look like (but are not) beta quartz is a superb, lustrous and translucent/transparent, rich emerald green fluorite octahedron, measuring 3.8 cm on an edge. The fluorite crystal is more sharply crystallized than most Riemvasmaak fluorites. Contacted on the bottom, but complete all around otherwise. Sitting flat as shown, or tilted up at... Read more
Unusually dramatic, this sculptural cluster of translucent quartz and fluorite is very different from others. A colorless, drusy quartz overgrowth has floated two, glassy and gemmy, light emerald green fluorite octahedrons, to 4 cm in length. It is easy to discern the outline of other fluorite crystals under the layer of drusy quartz, giving this piece an ethereal look. The specimen is thin (a con... Read more

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
of one of the listed collectors or institutions.
Searches are "bookmarkable". After clicking "Search", and
receiving results, you can bookmark the result page, and
your bookmark will store the search. Remember, revisiting the
bookmark will re-execute the search; it does not store
the search results. If the contents of the database have changed
