Bolivian Vivianite!


From the new find at the end of Summer 2004.  We are very proud to offer the first of what we consider to be some of the very best quality crystals of this species to ever come from Bolivia.  These crystals have without question the best luster of any Vivianite specimens to date from this country. Another outstanding feature is the wonderful color contrast between the vivid green Vivianite and the altered red sandstone . These pieces have what is some of the best matrix for these crystals from Bolivia. It's not unstable like decomposing Limonite and it provides a much more appealing contrast than ordinary Pyrite.  These pieces have outstanding sharpness, luster, aesthetics and color plus they are on a wonderful matrix.

 

Enjoy !!

Here is a great large doubly-terminated crystal from the find with some minor sandstone.  There is a contact on the bottom where it detached from the pocket.  It still is a great cluster, which is less common from this find.  This one looks better in person, it was simply difficult to photograph. 

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosí Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 10.2 x 4.7 x 3.2 cm.

This is a great gemmy, sharp, lustrous, vibrant green color crystal aesthetically sitting atop sandstone.  The display side is very beautiful and the piece is very reasonably priced because there is a contact on the reverse side where it detached from the pocket.

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosí Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 5.0 x 4.0 x 2.7 cm. (Crystal Size: 4.2 cm.)

VIVIANITE
on Sandstone - $300

This piece has great aesthetic form and a beautiful gem crystal flaring out of the side of a larger predominant crystal group.  All the crystals are exceptionally sharp, lustrous and gemmy with only a minor contact on the side-car crystal where it detached from the pocket.  One of the best pieces for the price I think.

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosí Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 7.2 x 6.3 x 3.7 cm.

This one is definitely a competition quality miniature.  You have it all with this piece.  A superb, sharp, lustrous, gem/gemmy doubly-terminated crystal aesthetically flaring off sandstone matrix.  The piece is virtually undamaged and about as showy as they get from this find.

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosí Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 5.3 x 3.8 x 3.7 cm. (Crystal Size: 5.3 cm.)

VIVIANITE
on Sandstone - $175 (SOLD)

The termination on this piece is what makes it so wonderful.  Most minerals don't form curved crystals like this, which is one of the great aspects of Vivianite.   There is a wonderful curved "fan"-shape group of crystals spinning towards another smaller group of crystals giving it a wavy appearance.  The overall quality on this one is superb. 

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosí Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 3.7 x 2.5 x 2.0 cm.

VIVIANITE
on Sandstone - $300

This piece has one of the most attractive twisted "sprays" flaring out of the side of a beautiful, sharp, GEM doubly-terminated prismatic crystal all sitting atop a very well balanced contrasting matrix.  The quality is very good on this piece and again, this one looks better in person than the photos would indicate.  One tiny "flea-bite" is the only noticeable damage we can find on the specimen. 

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosi Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 4.7 x 3.2 x 2.3 cm.

VIVIANITE
on Sandstone - $450

This large miniature size specimen has wonderful aesthetics.  The main crystal is a thick, very sharp, highly lustrous, gemmy deep emerald green "sword"-shaped prism aesthetically sitting atop a nice mound of contrasting sandstone.  The piece displays well without the aid of a stand or clay.  Larger crystals such as this are very hard to find with such great form and balance from this locality. 

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosí Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 6.0 x 5.4 x 3.7 cm.

An aesthetic, sharp, lustrous, gemmy crystal sitting atop sandstone.  There are a few minor nicks here and there, which is why the price is so reasonable.  A good buy for a piece this size.

Locality: Tomokoni adit, near Cañutillos, Colavi, Saavedra Province, Potosí Department, 36 km NE of Potosí, Bolivia.

Specimen Size: 4.7 x 2.6 x 2.6 cm.
