Wagholi Quarry, Poona, near Bombay, Maharashtra, India
Miniature, 3.4 x 2.5 x 1.3 cm
Cavansite is so common that sometimes one just tunes it out of the peripheral vision at shows in the big booths of Indian dealers. However, the truth is that GREAT cavansites are few and far between, the overall quantity has really slowed in the last few years, and certain pieces stand out above the rest. Most thumbnail cavansites are just "small rocks" or loose balls. This aesthetic matrix thumbnail specimen has both crystal habits, the spherical aggregates AND the elongated crystals, arranged elegantly on matrix and on the same specimen. It is, to me, a striking thumbnail specimen that displays real character that sets it above most small "representative" cavansites. I bought this and some other pieces in this update from the collection of Ernie Schlicter back around 2007, before it was sold. This is a large thumbnail/toenail sized specimen that displays fully in a TN box.
This is a remarkable cavansite. First, it's a near floater with just minimal contact at the base but otherwise complete all around, somehow. Secondly, it is a stalactite, and of a size quite rare for the species which normally occurs as smaller, dispersed clusters. Finally, it exhibits three different, and vivid, colors of royal blue hues, subtle shades within the overall first visual impression of "blue." Apparently, this specimen grew as a stalactite but I have never seen such a beast of a stalactite cavansite before - usually they are just thumbnails, or larger clusters maybe but with large contacts to matrix. This had to grow freestanding. Without a doubt, this is one of the most dramatic specimens of cavansite I have ever seen, especially for the size. Funny story, is that in Denver of 1997 or thereabouts I agonized over buying this specimen from Ken Roberts at his booth on the Main Show floor. It was so much money at the time, and quantity of cavansite had really just started to come out. Who knew what would come next? As remarkable as it was, it was a big chunk of my show budget at the time and I decided to sleep on it. Sure enough, when I came back the next day, Ken was wrapping it for Marty and it was gone. I always regretted not owning this specimen and so it was one of the specific pieces I angled for when the collection was dispersed. And...no more like THIS ever came out! Instinct proved right. 5.5 x 3.6 x 2 cm
Intense, royal blue, lustrous, translucent, bladed, cavansite crystals, to 2.0 cm across, are perched atop a matrix of soft, white, massive, stilbite. This is the most rare habit for cavansite here, and in person you can see how wildly different these pseudo-triangular blades are from the standard ball-shaped crystal aggregates.
This fine specimen is composed of lustrous, translucent, rich, teal blue clusters of cavansite emplaced on contrasting, white matrix of mordenite or powdery stilbite. The largest cluster of cavansite crystals is 2.0 cm across. Aesthetic and lovely! Looks like they are drip-dropping down the crevasse...In any case, certainly an unusually arranged specimen not like you normally see!
This cavansite cluster exhibits a rare stalactitic form and appears to be a floater, complete even at the bottom where it has crystallized around the base. The luster is vibrant, it is translucent, and exhibits a rich, teal blue color. The largest cluster is 1.5 cm across. As an added bonus, the whole piece is covered in minute, colorless, stilbite crystals. BEAUTIFUL and unusual cav specimen!
On a matrix of tiny, colorless, stilbite crystals, is a rosette of lustrous, translucent, deep teal-blue, cavansite which is 2 cm across. Additionally, on the stilbite, there are a couple of gemmy, yellow calcites, to .5 cm across. Beautiful miniature!
This is easily one of the LARGEST single clusters of cavansite that I have seen. The deep, teal blue color, bright luster, translucence, and the fact it is on matrix, make this a choice specimen. The big ball is wraparound, and just gives you loads of color for the price. Seen up close, it is crystallized, and not just a "ball," I should say. There is some minor edge wear at the bottom periphery, but otherwise its complete all around and really in astonishing shape for the size and exposure of the specimen. I have only ever seen such large cavansite clusters on much bigger (and pricier) matrices.
This is another fine and rare stalactitic specimen of deep, teal blue, lustrous, translucent, cavansite. At the wider base of this piece the radial pattern of cavansite is in evidence, measuring 2.0 cm across. A lovely miniature that is unique amongst the crowd!
This is a complete floater of deep, teal blue, lustrous, translucent cavansite, which is composed of crystal clusters to 1.3 cm across. In addition, there is a lustrous, translucent, colorless, crystal of stilbite, perched on the cavansite, which measures 1.0 cm in length. Very aesthetic.
This cavansite specimen has two clusters perched high on the stilbite and basaltic matrix. The cavansite is deep royal blue, has great luster, and the larger of the two measures almost 2.0 cm across. The luster is TOP quality here. The stilbite crystals are pearlescent and reach just under 1 cm. Note the unusual freestanding and isolated cavansite crystals at base.
A matrix of basalt has been covered by extremely, lustrous and gemmy, ivory colored stilbite crystals, to .4 cm across. Perched, aesthetically, on the stilbite is a rosette of deep, royal blue, translucent, lustrous, cavansite, measuring 2.5 cm across. The combination of the large, top colored, cavansite and glassy stilbite is an example of the very best these species offer.
This stalactitic specimen of cavansite is comprised of several 1-cm sized royal blue balls which culminate at the top with a deep blue sphere of over 2 cm. These all exhibit great luster. Such solid, elongated clusters of intergrown cavansite spheres are very rare!
Simply stated, this is a superior specimen! An elegant, curving cluster of cavansite balls, displaying the deepest royal blue color and almost iridescent luster, has grown across drusy, tan stilbite crystals. The largest ball of cavansite is over 2 cm across. In addition, the base of the specimen has a group of lustrous, doubly terminated stilbite crystals, to 1.5 cm. The color contrast of minerals and the 7 cm long, linear cluster of cavansite, easily make this specimen very desirable and FAR above the crowd.
A superb cluster of deepest, royal blue, cavansite, with irridescent luster is perched on a matrix of drusy, tan, stilbite. The color is as deeply saturated as they come. The cavansite cluster measures a whopping 4 cm across and 2 cm in depth. Except for minor bruising on the upper curve to the rear as shown, the cavansite cluster is perfect. In person, you just display it a bit more level with the undamaged side facing you, and it glows and shimmers like almost no other mineral. The piece LOOKS like it should cost a fortune, given the size and quality of the cav, but the minor bruising allows me to get it and offer it at a far lower price and thus it gives a LOT of bang for the buck.
Lovely and bright clusters of medium teal-blue Cavansite with a very attractive bladed habit (about an inch, or just over 2 cm!). This is very RARE to obtain, and the blades here are particularly large. Most often, cavansite forms spherical aggregates, rather than showing off the stereotypical crystal form as we have here. One of the advantages of seeing the blades so distinctly is the owner is afforded a sharp view of the superb, almost metallic, luster along the blades. A very interesting and fine specimen that is MUCH more electrically colored, in person! This is a rare treasure, even uncommon amongst so many other cavansites
Very nicely balanced specimen, with a beautiful 2.1 cm, teal-blue ball of Cavansite on just the right amount of matrix. The luster is excellent, and you can see the blade tips sparkle as the piece is rotated under the light. This is very RARE to obtain, with the isolated, larger cavansite crystals sticking out from the more traditional ball format. Most often, cavansite forms spherical aggregates, rather than showing off the stereotypical crystal form as we have here. One of the advantages of seeing the blades so distinctly is the owner is afforded a sharp view of the superb, almost metallic, luster along the blades. There is even a tiny white Stilbite on one side of the ball to add a little contrast. An excellent display specimen without breaking the bank, well-balanced on contrasting matrix!

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
