Bolivian Minerals Assorted $400 or Less
Page -
July 12, 2007
Here we have a nice group of less expensive mixed Bolivian
specimens (mostly phosphates with a few odds and ends) that simply did not find
their way into the previous update. All the specimens are excellent
quality and very affordable. Please click here if you wish to view
these pieces.

Bolivian Phosphates, etc. - June 2, 2007
Although Bolivia is known for its "black" minerals, there are plenty of
colorful, rather rare species from various localities. This part of the
update focuses on several phosphate species, and a few other non-phosphates that are
indeed colorful and attractive. This mix is a great representation of the
diversity of what Bolivia has to offer in terms of "non-black" minerals. Some of
these specimens are from older finds that have not produced similar specimens in
as long as ten years in some cases. Please click

these pieces.

Bolivian Sulfides and other Rarities - June 2, 2007

Bolivia produces a wealth of "black" minerals,
and despite the fact that some people refer to these specimens as "black uglies",
I personally like to refer to my black
rocks as "black beauties". Unfortunately they do not get the recognition that
they deserve, just because these are non-colorful species. Collectors
should not be deterred from these minerals as they are truly fine display
specimens. Several of the pieces in this section of the update are
exemplary in quality. The Potosiites are the finest crystals of the
species in the world, and the Stannites and Andorites are superb as well.
Collectors who appreciate the unique crystallography of many of these species
will be delighted to see what we've listed here. It's time to bring back a
love for "black" minerals, as they really give character to a collection, and
allow collectors to expand their horizons by obtaining very unique and rare
species in fine crystallized examples. Please click

these pieces.

Bolivian Cassiterite, Ferberite & Magnetite Mix -
June 2, 2007
This section of the update features some very
attractive specimens of a few oxides found at various localities in Bolivia.
Again, there are more "black" minerals, but I want to stress that these
specimens are very fine quality for the three species listed. Cassiterites
from Bolivia are some of the finest in the world, and the piece in this update
is very nice. There are many unique
Ferberite specimens (i.e., twinned crystals, crystals on matrix, crystals with
associations, etc.), and these are some of the best of what they are from
various finds over the years that I've been stockpiling from Tasna. The
Magnetite crystals in this update are as large as I've seen from the mine at
Cerro Huañaquino. Be sure to check out all these "black beauties", and
please keep in mind that they are difficult to photograph, so they actually do
look better than the photos indicate in most cases. Please click

these pieces.

Bolivian
Valentinites
Valentinite is Antimony Oxide (Sb2O3) and was named in
1845 after the mythical monk and alchemist Basilius
Valentinus. Some of these are "textbook", tabular,
monoclinic examples of Valentinite crystals as
illustrated in Atlas der Krystallformen by Victor
Goldschmidt. The luster and gemminess of these
crystals are superb. Not all the specimens have great
aesthetics or crystal size, but this is a rare mineral, and
with rare minerals come some good and some bad,
like all minerals. The only difference is that there are a
lot less of these in the world than a lot of other species.

Mixed
Bolivian Minerals

This is simply a
page of assorted specimens from various Bolivian
localities. Most of them are the only piece of a certain
type of specimen that I have for sale and they all
seemed to fall into the same category together.

Ludlamites
from Huanuni
 
These are some
of the best Ludlamites to ever come out of Huanuni.
Please note that this mine has not produced any Ludlamite specimens since about
2002, and they are becoming very difficult to find on the open market. I
have some more Ludlamites that I have been holding back for several years in the
hopes that more would come out, but since there are no new specimens available,
I will be posting more Ludlamites on the web soon!
|
|
Bournonites
from Machacamarca
 
The best of the
best to come out of the recent find at Machacamarca. I
have more of these specimens than any other dealer in
the country. Most of crystals are on matrix, and are
some of the finest Bournonites that I have ever offered
for sale from Bolivia. I have several more of these specimens which
hopefully will be posted to the website soon.

Gem Topaz Crystals From Pakistan
- November 5, 2007
Topaz Page 1
Topaz Page 2
I picked up this lot of single Topaz crystals in
Munich originally for cutting rough, but it turns out that many of them were
simply too nice to cut, so we decided to put together in a quick update.
There are no written descriptions for each crystal, just a size and a price, but
the photos are all good representations of the specimens. Truly, these
were not as easy to photograph as I thought they would be, but I think most
people are familiar enough with these pieces to know what the color looks like
(or should look like).Everything is priced at $300 OR LESS, so
they're all very affordable and excellent quality. Please click
here if you wish to view
these pieces.

(from under $100 and up) can be found on three pages. Please click

Chinese Spessartine !! - November
28, 2006
Over the last few years there have been some truly amazing
Spessartine Garnet specimens have been coming out of China. There is no
other modern locality producing such top shelf quality Spessartine crystals on
matrix in the world today. This is a great opportunity to obtain a piece
of this truly outstanding material (which seems to be dwindling in
availability) while the prices are still low. Every piece in this update
is unique and was hand-picked over the course of the last few years out of
literally thousands upon thousands of specimens. Please click

Pakistan Brookite,
Anatase & Rutile - October 30, 2006
Here we have a great selection of three trimorphs
of Titanium Oxide from the new "Alpine-type" cleft deposits in Pakistan.
These pieces are truly "Alpine" quality and rival famous finds throughout
Europe. It is nearly impossible to obtain crystals of any of these species
from the Alps, as they are highly sought after, and command a premium price in
Europe (that is, when they are even found), so the opportunity for collectors in
other countries is minimal to purchase superb representations of these minerals
for their collections. In some cases, these recent finds from Pakistan
rival and even surpass previous finds in the Alps in terms of size and quality.
The new Brookites are especially fine for the species, and it appears that the
locality that produced these specimens (along with the Anatase specimens) has
quickly dried up, so do not miss out on this chance to snag some great quality
minerals for a fraction of what they would cost from the Alps. Please click
here to view these pieces.

them are completely different from one another.

These are undoubtedly some of the finest Pentagonite specimens from any locality
in the world. There is an assortment matrix specimens with single and multiple
aggregates, along with fine single aggregates off matrix, and a great
combination specimen with Cavansite! These are also much more fairly
priced than comparable (and even inferior) specimens we have seen from other
dealers. Please click here to view
