A huge and very rich, museum-sized specimen of micro-crystallized yellow Tsumcorite (Type Locality) perched on small crystals of Quartz. Tsumcorite is a lead, zinc, iron arsenate and is named after the Tsumeb (Tsum) Corporation (Cor) Mine. The sparkly brownish-yellow Tsumcorite is one of the signature rare-mineral species for which the Tsumeb Mine is renowned and also the TYPE LOCALITY. The tiny T... Read more
This surprisingly large, well-terminated 4.5 cm Parisite-Ce crystal sits perfectly on a cluster of Microcline! Parisite is very rare for this famous, important REE-rich locale. The cream-colored Parisite is well-formed, in good condition, and exceptional for its size from any location, actually. The numerous, gray-white Microclines are euhedral, range up to 1.7 cm, and they have fantastic red fluo... Read more
Allenheads Mine, East Allendale, North Pennines, Northumberland, England, UK
Miniature, 4.1 x 3.8 x 3.2 cm
The term 'classic' certainly applies to the famous interpenetration Fluorite twins from England, including those from this well-known North Pennines mine (formerly named the Beaumont Mine). These lustrous and gemmy Fluorites have good purple color, and sparkly preferential coatings of lustrous Quartz crystals. The exemplary, large crystal is 2.7 cm, and it is zoned (evident when you look at the in... Read more
Bright, eye-catching specimen thoroughly dominated, and deservedly so, by a large, doubly-terminated Quartz crystal. This 3.3 cm crystal is so gemmy and lustrous that one can't help but think 'Herkimer Diamond' when looking at it. The flattened, translucent Quartz crystals are preferentially dusted by tiny Chalcopyrite crystals, which add a nice touch to the already good aesthetics. Unusual for lo... Read more
A fine Neudorf Galena specimen like this, with Siderites, would have been considered one of the top "holy grails" of sophisticated collectors of previous generations, and they should still be considered as such today, as well. All major collections had "a Neudorf" or desired to have one. Pieces of size and quality were always uncommon and this pristine and aesthetic piece meets both ancient and mo... Read more
Brilliantly colorful and lustrous Chalcopyrites grow en masse on this combination piece from this classic locality. The Chalcopyrites, which average 5-8 mm in size, have a natural luster that is so metallic and so bright it looks chemically induced (but is not). The colors range from brassy gold to silver, with flashes of red and purple. There are numerous faces and edges visible, and the Chalcopr... Read more
Herodsfoot Mine, Lanreath, Liskeard District, Cornwall, England, UK
Small Cabinet, 6.9 x 6.7 x 5.2 cm
Recovered in the late 1850s-1875, old-time Herodsfoot Bournonites are a worldwide classic. This showy and excellent specimen features lustrous, gunmetal-gray Bournonite cogwheels partially coated with glassy, textbook, dipyramidal Quartz crystals (typical for Herodsfoot). The Bournonites have a really nice iridescence - a natural, ancient patina. The striking cogwheel on the end is 2.8 cm across, ... Read more
Hasavarka, Prepolar Ural, Komi Republic, Northern Region, Russia
Cabinet, 11.5 x 9.0 x 8.8 cm
Russia was once known for its fine historic Amethyst locations, and in particular Hasavarka for it sceptered Amethysts - although they are very rarely seen for sale today. The crystals have good purple color with wisps of Smoky throughout, and the luster is superb. The outer zones of the Amethysts are quite gemmy and refractive, creating an additional 'sparkle' that adds even more to the aesthetic... Read more
Pohla is known for both its fine golden Barytes and Silvers. This superb, small cabinet piece features a pair of parallel-growth Barytes just over 5 cm long, both having excellent luster and incredibly gemmy, deep-amber terminations. The Quartz matrix just below is decorated with gemmy, 3 mm, lemon-yellow Fluorites that add the perfect touch to this aesthetic, and really quite dramatic, piece. Fir... Read more
Calcite and Quartz specimens are extremely rare from the famous mines at Neudorf (renowned for world-class Galena and Siderite specimens while calcite was quite rarely seen or preserved), and adding Chalcopyrite to the mix makes this even more unusual. Two upright, frosted, translucent, "nail-head" Calcite crystals to 4.5 cm are aesthetically set on edge on a plate of Quartz crystals, and the Calc... Read more
Valle de las Plumas, Paso de Indios Department, Chubut, Argentina
Small Cabinet, 8.5 x 8.3 x 6.4 cm
This striking, stellate cluster of sharp, pseudo-hexagonal Aragonite crystals has been pseudomorphed by Chalcedony and included by Hematite, which gives it its reddish-brown tone. The form is perfectly preserved, and there is some translucence at the terminations. The largest crystal is about 3.4 x 3.3 cm, and you have the luxury of choosing several good orientations for display. This is an outsta... Read more
A fine miniature Topaz-Smoky Quartz-Schorl combination specimen from the famous Klein Spitzkopje area. The 4 cm-tall Topaz is gem-clear and has the prototypical but rare, sharp crystal habit for here. It is complemented very nicely by a 4 cm-tall Smoky Quartz that is equally gemmy and lustrous. Both are included by Schorl needles, which makes for an excellent accent! I have never seen something qu... Read more
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
Spruce Claim, Goldmyer Hot Springs, King County, Washington, USA
Small Cabinet, 7.5 x 5.1 x 4.1 cm
Washington pyrites with their amazing striations and patterning, in association with quartz, are simply among the best in the world for collectors. However, few of them can compete for aesthetics or condition with material from other countries, and so these few, such as this, are highly prized. This well balanced piece shows off a complete, lustrous, brassy yellow pyrite cube, measuring 4 cm in le... 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

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
