Jeffrey mine, Asbestos, Les Sources RCM, Quebec, Canada
Thumbnail, 2.2 x 1.3 x 1.1 cm
This is a very good pair of Vesuvianite crystals from the quite famous, and now closed, Jeffrey Mine in Asbestos, Quebec. The rather unique Vesuvianites from there have aspects of Manganoan (purple) and normal (green/gold) varieties. The largest crystal measures 2.3 cm long, and both have good luster, well-formed terminations and attractive color. There is minor wear, but for the size and beauty, these are fine quality for the species
A well-formed, well-terminated Vesuvianite crystal from the famous Jeffrey Mine in Quebec. This Vesuvianite crystal has a glassy luster, good gemminess, and an almost iridescent green color that is not typical for the locality. At 5.6 cm, the size is exceptional, and the crystal is aesthetic. It is lustrous and complete all around, though it shows a strange and interesting "bend" in the middle, caused by growth changes in situ. This mine, long a source of superb minerals, is now commercially closed. Crystals like this are extremely hard to come by now and will only get more rare with age. This is a significant single gem crystal.
Monte Somma, Somma-Vesuvius Complex, Naples Province, Campania, Italy (TL)
Small Cabinet, 7.9 x 6.3 x 4.2 cm
This famous locality provided the first identified Vesuvianite back in 1795. This specimen is an old one, too - formerly in the Geology Museum of London (now merged with the BMNH). These gemmy, lustrous, root beer colored crystals range up to nearly 1 cm, and specimens of this quality from this location are so rarely available. They are so bright they look more like garnets and are practically gems, rare for the species. The basaltic matrix is green and microcrystalline, probably almost all made up of Augite or Olivine (Forsterite). An excellent, important specimen. Exchanged by Fioravanti in the 1970s.
The intense green color, due to an excess of chromium, makes these "chrome vesuvianites" from Asbestos unique in all the world. I would say that the Jeffrey Mine is deservedly the world's most famous locality for the best of this species. Many pockets were found over the years, but few stand out as "ikonic" among them. Only a few pockets were ever found, despite the thousands of tons of material mined here, of this incredible green variety of vesuvianite. This crystal, though repaired cleanly in the midpoint, is an exceptional example because it is an isolated single showing textbook form. For some reason, most of the chrome vesuvianite pockets have produced conjoined clusters of intergrown crystals, seldom with such individual definition to the crystals. This comes from a small private collection, self-collected (I believe it was in the 1980s), sold at Tucson in 2014.

This is a rich, cluster of 'Alpine cleft'-type Vesuvianite crystals with incredible luster. There are dozens of very sharp, highly lustrous, gemmy, "root beer"-colored prisms of Vesuvianite, the largest of which is .9 cm. These Vesuvianite crystals form a dense, aesthetic cluster, especially on the presentation side where they splay out almost radially. The crystals have gemmy terminations where you can see sparkles of the clove-brown color. Much better in person, even. These came only in a few pockets around 2009-2010.
Fine set of three sharp, individual Vesuvianite crystals, on matrix. The color is a deep cinnamon-brown with flashes of red, indicating some amount of gemminess. The luster on the striated faces is superb, with the terminations being complete, and frosted. The largest of the crystals is 1 cm tall and 1 cm across. An attractive specimen from a small find in Pakistan.
A well formed, doubly-terminated vesuvianite crystal "floater" with no visible points of attachment, this vesuvianite crystal exhibits glassy luster and good translucence with a beautiful green color. The basal termination has very minor bruising which is really of little significance, and is a bonus in any case to the top termination which is amazingly equant. This mine, long a source of fine crystals, is now commercially closed.
These come from the now-defunct Jeffrey Mine in Canada, which once was the largest asbestos producer in North America, I think. The color on this piece is amazing! Most are green, from here. The few that are purple, tend to be lavender colored or mixed with green tones. The brilliant glassy luster and deep purple color of this piece set it on a level apart from most (and ANY mn-vesuvianite is quite rare, really). Although the photos are good, the piece is actually quite a bit better and more 3-dimensional in person and a good bit more intense purple in fluorescent room lights than in halogen as photographed here. It is not pristine, but is nearly so, and certainly on the major crystals where it matters. This piece is from the Ken Rippere collection. Joe Budd Photos.
This is a beautiful combination of rich reddish, extremely large crystals of Vesuvianites sprinkled with many tiny gemmy garnets (hessonite) that form a glittering background to the upright Vesuvianite crystal. The Vesuvianites have excellent luster and classic vertical striations, as well as very fine and full terminations. The aesthetics of this piece are truly amazing and it is a world class example of this Italian classic. It really should be a miniature, if smallish perhaps. BUT, if put in a box diagonally, it can fit in a TN box. This is one of the finest such crystals I have seen for sale and is surely old.
A sharp miniature featuring a 3.5 x 1 x 1 cm crystal at one end that is super-lustrous and as glassy as these can possibly get, dominating the view as it rises above a cityscape of smaller crystals. The large crystal is pristine, and there are just a few trivial breaks (perhaps natural), on the smaller crystals. It is 3-dimensional and displays nicely, therefore, on both sides, all around. The termination is absolutely superb, as if it was faceted, and among the best I have seen on such a crystal.
This specimen clearly comes from the same pocket as the above, and features a super-lustrous crystal to 3.9 cm length. The termination is absolutely superb, as if it was faceted, and among the best I have seen on such a crystal.
An unusual specimen with a rare "pointy tip" on it, capping a complexly serrated , skyscraper-shaped cluster. The tips are perfect and pristine! The cluster is complete all around: The only contact is at the bottom, rear, base.
Overall, the finest vesuvianites in the world, both green and purple, came from this great open pit mine. Now closed, the mine produced few specimens of the aesthetic quality of this cluster: which is gemmy, lustrous, and has a very pleasing apple green color. The largest crystal measures 3.3 cm in length. Complete all around! This small group came from an old stash, and I expect few more such to show up on the market over time. THIS HAS BETTER COLOR, more green, in person!
This large and undamaged matrix specimen is covered with gemmy, lustrous, apple green crystals of vesuvianite, to 2.0 cm in length. There are also elongated 2mm crystals of an opaque, dark green, mineral scattered on several vesuvianite crystals, which have been analyzed as acicular groutite, a manganese oxide. This is a very good, relatively large specimen anyways, but the groutite adds a neat touch.
Deep wine-red crystals to good size, of the classic Italian vesuvianite! This is a large, fat, very lustrous and glassy crystal of high quality for the style! It is pristine save for one small ding or contact in the upper-right.
A limestone matrix and millimeter-size epidote form the substrate for a row of colorless, translucent, calcite crystals, the largest of which is 1.0 cm across. Aesthetically, nestled along side the calcite is a cluster of extremely lustrous, barrel-shaped prismatic, translucent red vesuvianite crystals. The largest reaches 1.0 cm across. The total effect, including the color contrast, is mesmerizing. IT IS MUCH BETTER IN PERSON and this is one of the better specimens I have sen far seen from new finds in Pakistan.
This material is a variety of Vesuvianite, that is sometimes called "California Jade." The name for this stone is actually pretty old, and dates back to the days of noted gemologist George Kunz who first described the material. At the time, he thought it was a new form of jade, but Vesuvianite is often confused for other minerals. This "Oval" cut stone is actually a very good quality gem for this material as it has great translucency, and amazingly rich color. The stone is a bit cloudy, but has a nice green color that shows up very well.
This rich, display-sized specimen hosts a number of elongated, sharply crystallized vesuvianites to nearly 2 cm. These are classic, forest-green vesuvianite crystals from the Italian Piedmont. Nice clusters like this have tended to stay in Italy with the collectors, and we seldom see (at least in the US) anything really good. Unique compared to other locales, these are immediately recognizable classics.

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
