Vivianite Specimens from the Tomokoni adit of the
Canutillos Mine, Potosi Department, Bolivia

These Vivianite specimens were first discovered in mid-2004, and I'm proud to say that we were actually the first US dealers to offer them for sale.  We were directly importing specimens straight from the mine, and had them out just a few weeks after they were discovered.  The specimens quickly sold out, and I was always hunting for more.  The locality hasn't produced anything in years, and by all accounts, it is completely finished. As luck would have it, while rearranging our store room, we recently found this beautiful parcel of specimens that have never been offered for sale.

These specimens are what I consider to be the VERY FINEST quality crystals of the species to ever come from Bolivia!  I've seen larger crystals, but I still contend that the Tomokoni specimens are superior in terms of quality.  The best of these crystals have without question the highest luster of any Vivianite specimens to date from this country.  Most Vivianite crystals from Bolivia (and around the world) tend to have a fairly matte luster, and are rarely bright and shiny like the pieces from Tomokoni.  Another important and impressive feature of these specimens is the wonderful color contrast between the vivid green Vivianite and the altered red argillaceous sandstone matrix which is not unstable like decomposing Limonite and it provides a much more appealing contrast than ordinary Pyrite.  As a matter of fact, Pyrite is the reason why many of the Vivianites from Bolivia are not very lustrous.  This stems from the fact the Pyrite will decompose / alter underground and essentially release sulfur which easily attacks the Vivianites, and causes them to become dull and dark.

Additionally, many of the crystals from this locality are rather gemmy with a beautiful green hue.  For those of you worried about Vivianites turning black, these specimens have been out of the ground for 15 years (at the time of this update) and still have excellent color.  The combination of the glistening luster, intense green color, and textbook crystals make them some of the most desirable examples of Vivianite that we've ever seen.

It should be noted that a large percentage of the specimens from this discovery were badly damaged.  Fortunately we were able to hand-select the best specimens when they were coming out of the ground, so we are offering better quality specimens than virtually anything that has been on the market.

Lastly, John Sinkankas said this about Vivianite in his book, Mineralogy:  "The goal of collectors in respect to Vivianite specimens is to obtain single crystals from the Bolivian localities".  John listed at least a dozen localities for Vivianite in his book and stressed that lustrous, gemmy crystals are almost impossible to obtain from any locality.  He also states that the "Crystals are seldom sharply terminated".  All of the terminations on the following specimens are very sharp and highly lustrous.

PLEASE NOTE:  All of these specimens were photographed with backlighting to better illustrate their internal gemminess and color.  With that said, Vivianites should only be exposed to light for limited amounts of time to prevent them from dehydrating.  It is recommended to store Vivianites in a closed box to preserve their quality.

Vivianite

Locality: Tomokoni adit, Canutillos Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 3.3 x 2.1 x 1.3 cm (miniature)


A rarely seen cluster of crystals of matrix from Tomokoni featuring several sharp, very well-formed, lustrous, gemmy, blue-green colored crystals of Vivianite on a small amount of red argillaceous sandstone. The best part of the specimen is that several of the crystals are actually doubly-termianted(!) which is not commonly seen in Vivianite. The largest crystal has a slight "bend" at the termination, which is not uncommon for Vivianite, but not typically seen from this locality.

Here we have an incredibly rare cluster of crystals from Tomokoni featuring thin, lustrous, gemmy, sharp "sword"-shaped prisms intermixed with contrasting red argillaceous sandstone. The majority of the crystals are undamaged, though there are a few contacts here and there. The crystals show a slight blue hue in areas when rotated in the light, which is due to their smaller size.

Vivianite

Locality: Tomokoni adit, Canutillos Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 3.6 x 2.6 x 1.3 cm (miniature)


An attractive group of "sword"-shaped Vivianites from Tomokoni with a bit of red altered sandstone at the base. A handful of crystals are contacted where they grew against the pocket wall, but a few of them are sharply terminated, and they all have excellent luster for the species. Additionally, a radiant green color can be seen when the piece is backlit.  These crystals show a slight "bent" habit, which is not uncommon for Vivianite, but is rarely seen from this locality.

Vivianite (notably "bent" crystals)

Locality: Tomokoni adit, Canutillos Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 3.6 x 1.7 x 1.6 (miniature)


A classic example of "bent" Vivianite in the form of a handful of sharp, lustrous, fine green color crystals with "sword"-shaped terminations and minor altered sandstone. Vivianite in an incredibly soft mineral, and it can often bend to create uniquely twisted or distorted crystals unlike virtually any other species. Combine that with the fact that the crystals are notably gemmy, and you have a one-of-a-kind miniature. Most of the crystals are undamaged, though the smaller accessory crystal on the side is contacted.

A very good single crystal of Vivianite from Tomokoni showing brilliant luster with sharp faces and a rich emerald green interior when backlit. The termination is completely undamaged, but the lower edge of the crystal is contacted where it was removed from the pocket wall. It stil remains a fine crystal of a species that is not typically found in such sharp and lustrous examples.

Locality: Tomokoni adit, Canutillos Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 4.1 x 2.8 x 2.0 (miniature)


One of the most aesthetic and finest quality matrix specimens of this material that we've had to offer. A fantastic, incredibly sharp, extremely lustrous, deep emerald green colored, doubly-termianted crystal group of "sword"-shaped Vivianite is beautifully set between two pieces of red argillaceous sandstone to create this wonderful miniature display specimen. No damage on the display side, and the only imperfection that I can see is a tiny bit of incomplete growth on the underside of the Vivianite where it was removed from the pocket. For the quality, balance, aesthetics, luster and color, this is a top-notch Vivianite for any collector.

Vivianite

Locality: Tomokoni adit, Canutillos Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 8.8 x 6.2 x 5.1 cm (small cabinet)
Crystal: 4.3 cm long


Isolated crystals of Vivianite on matrix from Tomokoni are notably hard to find, especially larger undamaged crystals like the one on this specimen. A razor-sharp, highly lustrous prism of Vivianite is lying in a semi-vug shaped indention of the red altered sandstone matrix. The natural shape of the host rock is what allowed such a good sized crystal to form and remain protected during growth. Normally a crystal like this would have grown against the pocket wall on the other side, and we wouldn't see the shimmering luster and beautiful textbook form. When backlit from the side, the crystal shows a strong emerald green hue. No damage, and just plain showy. A wonderful "hand"-sized display specimen from a locality where they were few and far between.

Locality: Tomokoni adit, Canutillos Mine, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia

Specimen Size: 10.6 x 2.8 x 2.1 (cabinet)


A remarkable cabinet sized Vivianite from this locality in the form of a sharp, lustrous, doubly-terminated, layered crystal group with a strong rich green hue when backlit. The piece has a bit of attached red sandstone matrix on the back, and it displays beautifully as you can see from the photos. To have a 10cm+ crystal from any locality is rare, and the fact that this piece is remarkably well-formed with top luster makes it all the more valuable.
