Huitzuco de los Figueroa (Huitzuco), Mun. de Huitzuco, Guerrero, Mexico
Small Cabinet, 6.5 x 3.5 x 2.25 cm
Originally described by Mariano Barcena in 1874. It is one of the finest specimens of livingstonite we've seen! Crystals on this specimen occur as aggregates of metallic, bright lead-gray, slender prismatic and columnar crystals, elongate  up to 2cm in length intergrown with stibnite. The back of the specimen is dark gray-black, and ocherous. Occurs in low temperature hydrothermal veins at this locality in Mexico. J. R. Jelks collection label.
Transparent, tabular, bladed, vitreous crystals of peretaite to 1mm associated with yellow, radiating sprays of klebelsbergite and a trace of kermesite lining vugs in a stibnite matrix. Very rare mineral and a superb specimen. From the type locality. Josef Vajdak label.
An aesthetic, imposing plate of bladed, iridescent metallic Stibnites. The luster is very good, and you can see occasional flashes of blue and gold as the piece is turned in the light. The blades average over 1 cm tall, the longest being about 1.5 cm, with varying widths. These Romanian Stibnites are classic, old European material, not to be compared on the same level to the far-more-common Chinese stuff available today! Aesthetic and quite substantial, considering it is rich and a full cabinet-size specimen.
An aesthetic plate of bladed, iridescent metallic Stibnites. They throw off amazing flashes of blue and purple colors as the piece is turned in the light. The blades average over 1 cm tall, with varying widths. Classic, old European classic material, not to be compared on the same keel to the far-more-common Chinese stuff available today!

Large Cabinet, 21.2 x 11.5 x 6.2 cm
An exquisite cluster from mining about 3-4 years ago that have by all acknowledgements produced the finest stibnites in the world since the ancient Japanese finds, now long gone. These brilliantly metallic crystals are so sharp and lustrous, they look machined. This particular specimen is one of the more robust clusters I have seen, with broad, fat crystals to 1 inch wide, in an elegant spray. It has the most trivial damage possible for such a large and exposed piece, and none of any significance. I looked through thousands of these, much of the find, and this was one of my favorite picks at ANY price and size range. Also, most of these are too large, if they are of any quality. This one is an excellent size for most collections, not too large, not too spindly-looking.
A very strang ecombination piece, that is quite complex in person, and is composed of barites, quartz-coated, ON a quartz pseudomorph after stibnite!

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
