Julcani District, Angaraes Province, Huancavelica Department, Peru
Small Cabinet, 8 x 4.5 x 4.5 cm
Visually scintillating combination piece from the well-known Julcani District in Peru. The blades of Enargite are significant in size - the largest being 5 cm long - almost unheard of for here. These blades are coated or partially replaced by lustrous, drusy Pyrite. Centered among the Enargites, rising like a Phoenix, is a brilliant, highly modified Pyrite pyritohedron. The luster on this crystal is superb, and the growth is so differential that one part rises well above the others, looking almost like an elongated spinel twin (but not). The Enargites are superb, and they are so enhanced by the dazzling Pyrite. For something so seemingly simple, I find the aesthetics of this small cabinet to be enthralling. In person, with the geometry and the sparkle and metallic shine, it is really just incredible and leaps out at the viewer. One of my favorites in this collection!
This outstanding thumbnail is highlighted by an upright, lustrous, striated, 2.4 cm crystal that is complemented by several smaller, sharp crystals and some Pyrite or Chalcopyrite. The termination of the main Enargite is tiered, smooth, sharp, and superb. Enargite is a Holy Grail mineral species for Butte and the Enargites from here are considered the best in the world. Excellent aesthetics, with just about perfect balance, makes this a super thumbnail example of this classic material from the 1950s or 1960s.
Stewart Mine, Butte, Butte District, Silver Bow Co., Montana, USA
Thumbnail, 3.1 x 2.1 x 1.6 cm
Enargite is a Holy Grail mineral species for Butte and the Enargites from here are considered the best in the world. This showy specimen is highlighted by an upright, lustrous, striated, 1.9 cm crystal that is complemented by several smaller, sharp crystals, all on a matrix of solid Enargites. The terminations on the Enargites are smooth, sharp, and superb. This excellent piece is from the Stewart Mine and is highly representative of the species and locale. Excellent aesthetics, not unlike the great Manganites from Ilfeld. More properly now, a "Toenail" in size. This is probably from the 1960s or prior times.
Jinguashi Mine (Chinkuashih Mine), Ruifang, New Taipei City, Taiwan
Cabinet, 13.0 x 10.3 x 3.7 cm
Wormlike elongated clusters of splendent, brassy yellow pyrite totally cover a matrix of crystallized enargite, here. In some cases the pyrite clusters are at right angles to each other, standing out nicely and giving this a very 3-dimensional surface. In general, fine mineral specimens from Taiwan are uncommon and this is an extremely showy piece from a classic mine (now defunct). Ex Eugene Sensel collection, from David New in 1975

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
since the search was originally stored, the results
