ex. John White
A fine elongated crystal spray of metavauxite, with a few sharp, individually more robust paravauxite crystals sticking out to the side. This looks great from the front, but has a little damage in the back to the termination, part of which is not present, hence the low price. But it LOOKS like a much more pricey thumbnail example, of this beautiful and very rare species. TYPE LOCALE!
5.4 x 4.0 x 2.8 cm. This piece features sharp, sparkling, lustrous, light green crystals of Paravauxite measuring up to 6 mm on matrix.
21.6 x 9.4 x 5.8 cm. From the new find of 2006, this is undoubtedly one of the most significant and momentous discoveries ever made at this locality. Not since the days of World War II has there been such a remarkable find of this material. These are simply put, some of the largest overall Vauxite specimens in the world, but the greatest aspect of these pieces is two-fold. First, the Vauxite itself is associated with micro fibrous "strands" of the super rare phosphate Metavauxite, plus tabular micro crystals of Paravauxite and small whitish spheres of Wavellite which means that these are just a dream for phosphate collectors. It is incredibly rare to have FOUR individual phosphate species all on one specimen, and the fact that this mine is the TYPE LOCALITY for Vauxite, Paravauxite and Metavauxite makes it all the better. There are also some small gem Quartz crystals on most of the specimens found as well, which is really a nice touch to these already amazing pieces. The second significant attribute of these specimens is the fact that they formed on a solid Quartz-Diorite porphyry matrix, and not crumbly clay (after Allophane) which means that they are much sturdier and allows the pieces to be displayed with ease. Now you must note that despite the sturdy matrix, the crystals themselves are somewhat brittle and must be handled with care. Nonetheless, this is a MAJOR find of these incredibly rare minerals, the likes of which I’ve never seen from Bolivia, or any other world locality. This particular piece is a remarkable, large, very well crystallized, ridiculously rare, specimen consisting of small, bladed, beautiful blue color, radiating aggregates of Vauxite associated with micro fibrous strands of colorless Metavauxite, along with micro tabular blades of Paravauxite and small whitish spheres of Wavellite plus a few scattered gem quality Quartz crystals on firm Quartz-Diorite porphyry matrix. I have photographed the Vauxite crystals under high magnification to show that they are truly terminated crystals and not just a blue mass. I have also photographed the Paravauxite and Metavauxite crystals under the microscope. It is very difficult to obtain any specimens of this incredibly beautiful phosphate and to find all three "Vauxites" together on one piece is amazing. This piece is from the type locality for Vauxite, Paravauxite and Metavauxite which was discovered along the Contacto and San Jose veins in this mine and was first described by Sam Gordon and Mark Bandy. It is so unbelievably rare to find good size, beautifully crystallized matrix specimens of Vauxite from Bolivia like this one.
8.0 x 4.5 x 3.4 cm. From the new find of 2006, this is undoubtedly one of the most significant and momentous discoveries ever made at this locality.

5.3 x 2.4 x 1.7 cm. These crystals are one of the most beautiful phosphates in the world. They are highly prized for their rarity and beauty. This remarkably large specimen features an attractive group of lustrous, water-green color Paravauxite crystals and some minor tan color Sigloite crystals on matrix. Sigloite forms as an alteration of Paravauxite. The largest Paravauxite crystal measures up to 1.7 cm. This specimen is from the type locality for both species ! Mark Chance Bandy described Paravauxite crystals in his book "Mineralogy of Llallagua, Bolivia". He states that Paravauxite is the most abundant of all the "Vauxites" from this mine," and with that said, you almost never see specimens, especially pieces that are larger than thumbnails available on the market. This piece is a great example of the prismatic, sheaf-like parallel growths that Mr. Bandy described. To find a piece of this size with so many great quality crystals is unheard of these days.
10.5 x 7.8 x 4.0 cm. This remarkably large specimen features an attractive group of lustrous, water-green color Paravauxite crystals and some minor tan color Sigloite crystals associated with micro crystallized iron-stained Wavellite needles on matrix. Sigloite forms as an alteration of Paravauxite. The largest Paravauxite crystal measures up to 0.7 cm. This specimen is from the type locality for both species!

4.0 x 2.0 x 1.6 cm. These crystals are one of the most beautiful phosphates in the world. They are highly prized for their rarity and beauty.

4.3 x 3.2 x 2.4 cm. An aesthetic, old-time specimen of two, fan-like clusters of lustrous, pastel-green paravauxite blades very nicely set on matrix. Ex J. Cilen and George Elling Collections.
6.1 x 5.1 x 1.6 cm. From the new find of 2007, this is another great discovery for this locality. This particular piece is a remarkable, very well crystallized, ridiculously rare, specimen consisting of small, bladed, beautiful blue color, radiating aggregates of Vauxite associated with tabular blades of Paravauxite on clay matrix. It is very difficult to obtain any specimens of this incredibly beautiful phosphate and to find all two "Vauxite" species together on one piece is fantastic. This piece is from the type locality for Vauxite and Paravauxite which were originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy. It is so unbelievably rare to find good size, beautifully crystallized specimens of Vauxite and Paravauxite together from Bolivia like this one.
4.8 x 3.7 x 1.7 cm. Here we have a remarkable, very well crystallized, OUTSTANDING blue color, ridiculously rare specimen consisting of radiating crystal aggregates of Vauxite associated with minor light green Paravauxite on clay matrix. I have photographed the crystals under high magnification to show that they are truly terminated crystals and not just a blue mass. I must point out that these crystals of Vauxite show the most electric neon blue color that I''ve seen for the species, but it appears that the rich color is actually due to a micro coating of transparent Quartz on top of the Vauxite. It is very difficult to obtain any specimens of this incredibly beautiful phosphate, but this color is simply unheard of. This piece is from a NEW FIND at the type locality for this material which was originally discovered along the Contacto and San Jose veins in this mine and first described by Sam Gordon and Mark Bandy. It is so unbelievably rare to find matrix specimens of Vauxite.
2.6 x 1.6 x 1.2 cm. This piece features superb, sharp, sparkling, lustrous, light green crystals of Paravauxite on a thin layer of clay matrix. Collected in September of 2007 and brought to the United States by Brian Kosnar.
9.8 x 5.1 x 2.1 cm. From the new find of 2006, this is undoubtedly one of the most significant and momentous discoveries ever made at this locality.

8.8 x 3.6 x 2.6 cm. These crystals are one of the most beautiful phosphates in the world. They are highly prized for their rarity and beauty. This piece features superb, incredibly rare, sharp, sparkling, lustrous, light green crystals of Paravauxite measuring up to 8 mm on micro Wavellite matrix. This specimen is from the type locality for the species! Mark Chance Bandy described Paravauxite crystals in his book "Mineralogy of Llallagua, Bolivia".
