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 on matrix. This specimen is from the type locality for the 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. 7.2 x 4.5 x 2.8cm
A superb toenail or large thumb, with a 1-inch rosette or bowtie of unusually large paravauxite crystals. 2.4 x 2.2 x 2 cm

This piece features superb, incredibly rare, sharp, sparkling, lustrous, light green crystals of Paravauxite measuring up to 8 mm on matrix. This specimen is from the type locality for the species !

This specimen features an intergrown nest of lustrous, light-green color Paravauxite crystals associated with spherical micro crystallized iron-stained Wavellite needles on matrix. The largest Paravauxite crystal measures up to 0.4 cm. The Siglo XX mine (Twentieth Century mine) in Llallagua, Bolivia is one of the most prolific localities, and one of the greatest tin mines in all of Bolivia and the world. This is an unusual ore deposit because of the fact that high temperature metallization took place at such a shallow depth. This mine is truly one of the most unique localities in the world from the standpoint of mineralization. This mine is the type locality for this species 4.6 x 3.2 x 1.6 cm

A superb bowtie of fine blades of rare Paravauxite from finds of probably 60-70 years ago in the days of Mark Bandy. The individual blades are lustrous and partially gemmy, and the overall effect of the specimen is graceful and delicate. This complete-all-around thumber is superb for the species!
ex. Martin Zinn
A huge, unusually fat, doubly-terminated crystal of this very rare species on matrix! It measures 2.2 cm! This is truly exceptional for the species.

A VERY RARE COMBO SPECIMEN! These two species were first described on an expedition to South America, about 1930, by Sam Gordon, then curator of minerals at the Philadelphia Academy of Natural Sciences. Laths of doubly terminated, lustrous and translucent, pearlescent, paravauxite, to 1.1 cm across are enhanced by .3 cm rosettes of royal blue vauxite. Stunning contrast found only on old specimens recovered in that era.
ex. Philadelphia Academy of Natural Sciences
A rich plate with DOZENS of sharp, translucent, beautiful crystals running all over it, to 1.2 cm in length; and many of which are doubly-terminated. A vein of some white phosphate material runs through the middle. Despite its size, this plate, and the crystals on it, are largely unscathed. The piece is quite displayworthy and comes with a nice original label. Almost certainly this was field-collected on one of the famous Vaux expeditions in the early 1900s. TYPE LOCALITY MATERIAL: Paravauxite was described in 1922.

A rich plate with DOZENS of sharp, translucent, beautiful crystals running all over it, to 1.2 cm in length; and many of which are doubly-terminated. A vein of some white phosphate material runs through the middle. Despite its size, this plate, and the hundred-plus crystals on it, are largely unscathed. Coverage on the back is more sparse, but with larger crystals to 1.75 cm. The piece is quite displayworthy and comes with a nice original label. Almost certainly this was field-collected on one of the famous Vaux expeditions in the early 1900s. TYPE LOCALITY MATERIAL: Paravauxite was described in 1922 and so it is not a huge leap of faith to assume this specimen and others in the Academy collections came from some of the same sources at the same time as the type study material.
An extremely fine and relatively large plate of excellent, rare crystals of this phosphate species. They reach 1 cm in length and have the classic pastel green color. Thi remarkably rich, large plat eis from the personal collection of dealer Richard Kosnar #331

A superb toenail or large thumb, with a 1-inch rosette or bowtie of unusually large PV crystals. This is a super specimen of rare quality for this species!
First discovered here in the 1920’s and named by Sam Gordon, of the Academy of Natural Sciences in Philadelphia, this rare phosphate has gemmy light green acicular crystals with superior luster. Although small overall, the specimen features exquisite crystals of unusually good form, translucence, and sharpness and is thus of higher quality than one might otherwise think.

An extremely rich, attractive specimen with crystals to 1.2 cm, of this very rare mineral from its type locality. Seldom do we see such an aattractive large group of paravauxite. Joe Budd Photos.

A historic, published piece of huge significance from the noted collection of William S. Vaux (1811-1882)...This old-time matrix specimen is covered by tannish, metavauxite crystals, on quartz to .5 cm in length. Metavauxite is a rare hydrated iron, aluminum phosphate - the most rare of the related minerals metavauxite, paravauxite, and vauxite. There are also a few crystals of sheaf like, pastel-green paravauxite, to one 1.0 cm in length. Both of these species were named by Sam Gordon, around 1930, in honor of his patron George Vaux, nephew of collector William Vaux. So here we have a sentimental specimen linking the curator of the museum to the family that funded his expeditions in the museum's heyday before its decline in modern times, and the specimen in question also CAME FROM the original older museum expeditions funded by the uncle, a major supporter of the museum since its earliest days. Accompanying this specimen is an original copy in decent condition of the 1944 proceedings of the Academy of Natural Sciences of Philadelphia, where this specimen is photographed as plate 25. Historical, old, and important specimens are too rarely available these days, especially with such interesting documentation. More than that, this is on its own merit a cabinet specimen of a very rare species, in rich quantity.
