This is a major locality piece from an old and famous locale, and formerly in the collection of the Harvard Museum (exchanged out to Phil Scalisi long ago). Nestled aesthetically in a vug is a particularly fine, glassy and translucent, snow white crystal of analcime, measuring 5 cm in length. A few crystals of tan, lustrous heulandite, to 2.5 cm in length, are also present on this highly aesthetic and unusual specimen. The analcime has a brightness and luster that would make it stand out from ANYWHERE, but I have not seen one so good from here for sale. Ex Harvard and Scalisi, with labels.
Poudrette Quarry, Mont Saint-Hilaire, Quebec, Canada
Small Cabinet, 5.5 x 3.5 x 3.2 cm
A classic combination piece from the great mines at Mont Saint-Hilaire. The Serandite-Analcime combination is one of the most famous, and highly desired, combinations, and both are excellent here. Good form and luster are hallmarks of both species here, with the flesh-colored Serandite blades reaching 5 cm and the largest, complex, euhedral Analcime reaching 1.3 cm. In combination there are white, pearly blades of Polylithionite (Mica group) that fluoresce a brilliant white. There are also tan crystal sprays of an unknown mineral (Pectolite, Calcite?) that fluoresce a modest red. The Aegerine (Acmite) blades exceed 1.5 cm, and may even reach 2 cm. This is a distinguished and aesthetic combination piece from famous Mont Saint-Hilaire. Obtained in trade by Dr Art Soregaroli from the National Museum of Canada in 1991.
Junnila mine, New Idria District, San Benito Co., California, USA
Miniature, 3.5 x 3 x 2.25 cm
A 1.2 x 1.1 x 0.3 cm fresnoite crystal stands dramatically upon contrasting matrix here! Fresnoite is among the rarest of the San Benito County mineral suite, perched on contrasting matrix of small analcime crystals! The world's best fresonites, undisputedly came from a small region near the benitoite mine in this region, in particular the Junnila Claim. This is from the find of Scott Kleine in about 2002, called the "4th of July Pocket." It resided in his collection for some time, and I always felt it was one of the better miniatures in the find (and thus for the species).
Analcime is one of the few Zeolites that forms in gemmy enough crystals for faceting. The Bay of Fundy area in Nova Scotia has been known to produce gemmy crystals of Analcime, though not very big. This stone actually looks a bit better in person, and was a real chore to photograph. Because the photos magnify to gem so much, they make it looks heavily included, and the stone actually faces up fairly well with moderate inclusions. The stone has an Oval cut, and is gemmy in areas. One does not often see gem quality Analcime (especially in this size !) on the market anymore as most localities produce chalky white crystals that rarely show any gem areas whatsoever. This stone would make a nice addition to a rare colorless stone collection, a Canadian gem collection, or even a facetted Zeolite suite.
White Mountain, Legional County, Antrim, Northern Ireland
Cabinet, 10.3 x 9.7 x 4.6 cm
An unusually large plate of fine analcime crystals in a basalt pocket from this seldom-seen locality, featuring one central crystal that is 3.2 cm across. Minor natrolite is in association as well. The piece is large and significant. Ex RFD Parkinson collection in 1965 to the Ted Johnson collection.
Exceptional crystals for this locality, of this rare zeolite species. Seldom found at any US locality in good size, let alone from the historic copper mines of Northern Michigan. In fact, this is a highly unusual environment and association for them to form in, but there they are. The crystal in center is 3 cm, not counting the sidecar to its left. Seldom do you see a crystal of this magnitude, though. From the late Ernie Schlichter's noted Copper Country sub-collection. Joe Budd Photos.
A glassy, translucent, snow-white crystal of analcime, measuring 3.4 cm across, is aesthetically perched high on matrix. Superb locality example, and better than other (smaller) specimens I have personally seen from here in the past. Self-collected by Robert Fender many years ago (probably circa 1960s-1970s). Surprisingly, this ranks up there with analcime from Mt St Hilaire, and I had no idea that the Parrsboro area produced this quality.

This stone actually looks much better in person, and was a real chore to photograph. Because the photos magnify to gem so much, they make it looks heavily included, and the stone actually faces up quite well with only moderate inclusions. The stone has a "Cushion" cut, and is what would be considered "gem quality." One does not often see gem quality Analcime on the market anymore as most localities produce chalky white crystals that rarely show any gem areas whatsoever. This stone would make a nice addition to a rare colorless stone collection, a Canadian gem collection, or even a facetted Zeolite suite.

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
