Vivianite from the Tomokoni adit,
near the Cañutillos mine, Bolivia
These specimens represent some of the better
specimens I held back after the find at the end of Summer 2004,
in the hopes that there would be more. Alas, no more have been found,
and it seems that this locality will not produce any more of the
specimens. I was very proud to offer the FIRST of what I 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 I think 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.
I cannot stress how exciting these Vivianite specimens truly
are. These pieces have such outstanding aesthetics, color, quality
and gemminess. I have seen hundreds of Vivianite specimens from
Bolivia in my life and these pieces sent my heart pounding when
I first saw them.
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 "Crystals are seldom
sharply terminated". The terminations on the following specimena
are very sharp and highly lustrous.
Enjoy !!

piece is a rather rare matrix specimen for this find. The thick
red Sandstone matrix hosts a very attractive, sharp, lustrous,
gemmy, emerald green color, doubly-terminated crystal. For the
overall size, aesthetics and quality, this is one of the best
small cabinet specimens that I purchased.

Here
we have a very good sized crystal from this find showing very
sharp faces, high luster, and rich emerald green color. The
crystals has attached red Sandstone on the back, showing where
it was attached to the matrix, so it is not totally perfect
all the way aroudn, hence the lower price. A very good representative
crystal from this find.

Most
of the Vivianite specimens from this find were either single
crystals or isolated crystals on matrix, so to find a beautiful
"fan like" cluster such as this is rare. This piece hosts several
gorgeous emerald green crystals, many of which are water clear,
and have very sharp, lustrous faces. Some minor associated red
Sandstone makes for a beautiful color contrast.

Vivianite with BARITE ! -
$225
Less
than 1% of ALL the specimens from this were associated with
Barite, and this is one of the very few specimens of this material
that I purchased. Inside a vug of red Sandstone lies a sharp,
lustrous, dark green Vivianite associated with many small, white,
bladed Barite crystals. This is a rare association from Tomokoni,
and this piece would make a great addition to ay Bolivian reference
collection.

This
piece is a rather rare "fan like" group of emerald green color,
sharp, lustrous, very gemmy Vivianite crystals on minor red
Sandstone matrix. It is easy to see that this is a very aesthetic
miniature specimen. Despite the fact that one of the crystals
on the top is not terminated, the rest of the crystals are virtually
pristine. It is very rare to find such an aesthetic group of
crystals on matrix from this locality.
