An incredible anatase for Brazil or any worldwide locale! This huge, silvery gray-blue, ditetragonal pyramid of anatase from Diamantina, Brazil is 1.9cm wide and a full 3.9cm long...unheard of in this size and quality from this occurrence. Diamantina is generally noted for its beautiful specimens of rutile, another titanium dioxide polymorph. The crystal is very lustrous save local dull patches that can be seen on the photos, and some evident edge wear and a few nicks. Given the rarity of such a thing, I can accept those minor detractions. Ex. Lawrence Conklin collection with label. He told me that he got it decades ago from the AMNH museum. I have never seen such a beast of a crystal from Brazil.
Impressive single crystal of Anatase from the classic locale! While many have an equally good luster and form, to find a 2 cm crystal in such exquisite condition is quite unusual. A desirable thumbnail, with very good aesthetics.
A large, isolated anatase perched on just a small pedestal of matrix - very aesthetic. It is almost perfect, with a ding in the upper-left corner depending on how you display. Hence the price is reduced, but it sure looks at first glance like it should cost a heck of a lot more.
The Norwegian Anatases are considered the world's best, and this 1.5 cm crystal well-represents the species. The luster of this flat-topped crystal is excellent, and there are but a few minor bits of edge wear. It is in excellent condition, and sits nicely on the matrix whereas usually they are only loose singles. A very fine, aesthetic small cabinet specimen.
An exceptionally sharp single crystal, showing gemmy blue and tan highlights around the edges, superbly representing the rare but superb anatase to have come out of Pakistan in a trickle over the last year or so. This piece is sharp, glassy, and all around top quality!
This bizarre specimen features a very unusual hollow anatase crystal of 1.5 cm next to an adjacent crystal of more typical habit. I have never seen anything quite like this. It is possible the anatase we see is a cast after an earlier generation, or even after a zircon perhaps, but I am not sure. The crystals sit on a quartz crystal (broken at either end but intact on the display face). In any case, the material has been analyzed and it is anatase now - a whopping huge one for Brazil, I would say. (obviously not a Jonas tourmaline but it fit in well with this update and was also at Munich...)
Mount Storenut, near Hardangervidda, Hordaland, Norway
Miniature, 3.5 x 2.8 x 2.1 cm
Outstanding, and truly first-tier, combination piece of a fabulous Anatase balanced upon a gemmy, pristine, Quartz crystal. Normally, the Anatases you see associated with Quartz are less than 1 cm, but this lustrous, euhedral bipyramid is an astounding 2.7 cm in length. The presentation faces are shiny, striated, and very sharp. There is some contacting on the base of the reverse side, but that is where it grew against matrix and it is otherwise complete. Considering the sharp, gemmy Quartz, and the magnificent Anatase-of-huge-size, this is just a killer! To me, it is one of the finest pieces in this collection. It is a toenail sized specimen (either a large thumbnail or a small miniature depending on how you angle it for display) ex Sam Nasser collection. Specimens like this are stunning examples of this unusual species, seldom seen. It is top tier.
The presence of mirror-bright faces on a well formed 1.9 cm long, dark gray, anatase crystal, help make this specimen an unusually aesthetic piece. In addition, the anatase is aesthetically emplaced on a druse of nearly colorless quartz crystals. A minor bruise on the back of the anatase termination is not visible when the specimen is properly oriented, and overall this is a superb miniature.
Thumbnail – Maximum 3.0 cm
Toenail – A “gut feeling” but often overlaps between a large thumbnail and a small miniature
Miniature – Maximum 5.0 cm
Small Cabinet – Maximum 9.4 cm
Cabinet – Maximum 18.0 cm
Large Cabinet – Over 18.0 cm
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
