Very rare combination featuring
Argentite ps. after Galena with Realgar and Xanthoconite crystals on Barite!
Xanthoconite is a rare Silver Arsenic Sulfide (Ag3AsS3).
These rare specimens came to market years ago and
only a few good ones were available at that time. They've long since disappeared and I
haven't seen one in
almost a decade. The Xanthoconite can be seen scattered about atop the Barite blades near
the Argentite
which has completely pseudomorphed and taken on the habit of the Galena cubes. Red
Proustite crystals
are also present on this unique Silver specimen, displaying a close association with the
Xanthoconite.
From the Alte Hoffnung Gottes Mine, Kleinvoigtsberg,
Freiberg District, Erzgebirge, Saxony, Germany.
Measures 7.5 cm by 5.5 cm by 4 cm in total size.

Scarce specimen featuring spheres of
Native Mercury atop red Cinnabar!
I seldom come across examples of Native Mercury at
the shows so specimens don't make
it to my website very often. Mercury is the only mineral that I know of that is liquid
at room
temperature and is an absolute must for any Native Element collection. This is a
beautifully
preserved specimen featuring several dozen mirror-like drops of Mercury atop the Cinnabar
and shiny matrix. Looking at the surface with a 16x magnification shows the heavy
coverage!
From the Socrates Mine, Castle Rock Springs area, Mayacmas
Mts, Sonoma County, California.

Exceptional
specimen featuring large crystals of Native Copper!
The large triangular crystal
on the top measures 3.5 cm in size! Smaller crystals measuring to nearly 3 cm
form the majority of what is a large dendritic-styled growth pattern. The Copper surfaces
are lustrous with an
attactive reddish-brown patina. The specimen is very asethetic and the crystal placement
makes it 3-dimensional.
From the Ahmeek Mine, Ahmeek, Keweenaw Peninsula, Michigan.
Measures 9.6 cm by 4.3 cm by 4.4 cm in size.

Unique specimen featuring flattened Azurite
nodules on matrix!
A collection of these unusual specimens appeared in Tucson a few years back and quickly
disappeared
from the market. This is best example I've seen since then and the 4.5 cm Azurite nodule
is one of the
largest I've offered on the website. A couple of smaller nodules accent the hard Kaolinite
matrix. The
flattened Azurite is actually crystalline with crystal faces at the edges. It was forced
to grow outwards by
the narrow spacing between the Kaolinite layers but this accounts for the unique form and
satiny luster.
From the Malbunka Copper Mine, Areyonga, Alice Springs, Gardiner Range, Northern
Territory, Australia.
Measures 11.3 cm by 9.5 cm by 5 cm in total

Unique PSEUDOMORPH specimen featuring
Goethite ps after Selenite crystals!
Visually this specimen is quite impressive. The brown Goethite pseudomorphs the Selenite
crystals
and accurately displays the crystal habit despite the difference in appearance. The
largest of the
pseudomorphs measures nearly 8 cm in length! The interiors are hollow and cast-like in
structure.

Brilliant crystal of transparent
Selenite set among Gypsum matrix!
Perfectly terminated and measuring nearly 10 cm in
length, this Selenite has a lot of pizzazz
for such a common mineral. The surfaces are superbly striated, giving the crystal an
amazing
sheen or luster. The termination is fine with only a small bit of irregularity on the
right side. Other
smaller Selenites pop out here and there from the yellowish-tan Gypsum matrix. Very
fluorescent!
From Santa Eulalia, Chihuahua, Mexico.

MIN#Denver2013-33 New!
Brilliant specimen of Native Wire
Silver on Acanthite and Quartz matrix!
This specimen caught my eye immediately and
I've seen more Moroccan Silvers than I can
count probably. I think it's the intense luster and beautiful toning that attracted me to
the piece
first but I also like the way the wires curl around at the very top of the Quartz and
Acanthite
matrix. The Acanthite appears to be a combination of crystals and epimorph form shaped by
the
Quartz matrix. The Acanthite is quite lustrous and appears mainly at the edges and back
side.
From the Imiter Mine, Imiter District, Djebel Saghro,
Ouarzazate Province, Morocco.

Attractive plate of Enargite crystals
with fine Quartz needle clusters!
This is one of those "black uglies"
that is actually pretty good looking. The crystals are
much sharper than normal and evenly spaced atop the plate. The surfaces of the crystals
are incredible flashy with an intense sparkle in even faint lighting. Small clusters of
fine
needle Quartz provide the perfect accenting along the top edge. This is a superb
miniature.
From the Stewart Mine, Butte, Silver Bow County, Montana.
Measures 8.5 cm by 6.8 cm by 2 cm in total size.

Fine specimen of Chrysocolla with
Azurite, Malachite, and Tenorite!
This specimen has a little of everything and
the various colors forming the textured surfaces are
evidence to this fact. The blue Chrysocolla pops the most along the bottom half and is
covered with a
silky luster. The Tenorite is present as the dark, almost black mineral coating in the
deeper recesses.
From the Morenci Mine, Morenci, Copper Mountain District,
Shannon Mts, Greenlee Co., Arizona.

VERY RARE and historic specimen of
crystalline Native Gold on altered Rhyolite matrix!
A very rich specimen of Native Gold from a locality
that is tied to one of the most famous ghost towns
in America - Rhyolite, Nevada! The photo above shows the brilliant Gold crystals which are
bright in
color and very lustrous. The matrix is typical to the Bullfrog District and matches the
material I've
personally dug many times while exploring the Rhyolite area. This specimen dates to the
early 1900s
and was displayed in the Beatty Exchange Club for years until it was donated to the
Keck Museum.
I've only seen three specimens of Gold from the Rhyolite District and two of those are in
this update.
From near Rhyolite, Bullfrog District, Nye County, Nevada.
Total specimen weight is 57 grams.
Measures 4.5 cm by 2.2 cm by 3.5 cm in total size.

MIN#Denver2013-38 New!
Aesthetic combination featuring Quartz
crystals with a Ferberite blade!
The Ferberite is perfectly terminated with an
intense rolling luster that streams from one
striation to the next down the length of the crystal. It sits perched atop a cluster of at
least
half a dozen terminated Quartz crystals with an attached smaller Ferberite to the lower
left.
The eye appeal of this specimen is dazzling and the Quartz crystals are super clear and
glassy.
There are some small bumps along some of the tips but these get lost in the flash of the
cluster.
These specimens have become very scarce in recent years. This is from an older collection.
From the Kara-Oba W deposit, Betpakdala Desert, Karagandy
Province, Kazakhstan.

The "SILVER COBRA"!
This is truely an EXCEPTIONAL specimen of Peruvian
Native Wire Silver on matrix!
Peruvian Silvers hit the market about ten years ago and they really came on strong and
heavy
at the time. Unfortunately, I didn't find very many with the aesthetical quality of this
well known
specimen. The piece was photographed by Jeff Scovil at the time for publication and it was
named
the Cobra for obvious reasons. Unlike so many Peruvian Silvers, these wires are thick and
clean.
The luster is also very impressive. I consider this one of the finest Silvers to come out
of the find.
From a private collection, this is the second appearance of this fine specimen on the
website!
From the Uchucchacua mine, Oyon Province, Lima
Department, Peru.
Measures 5 cm by 6.5 cm by 5.2 cm in total size with a "snake-like" 3.5 cm curl
of Wire Silver.

Large, impressive cluster of Milky
Quartz crystals with green Chlorite inclusions!
This is the largest Milky Quartz I've ever
seen from Mt. Ida and honestly, I haven't seen very many
as most that are found there are transparent, colorless rock crystal. The huge point on
the left measures
21 cm in length while the crystal point on the right measures nearly 26 cm! Nestled
between the huge
points are numerous smaller crystals and these are present on the back side as well. The
left crystal
changes over to a nearly transparent Quartz near the top termination but the right crystal
is all Milky
with a wonderful glassy luster covering the white cream surfaces where the Chlorite is not
present.
There also appears to be a scepter or attempt at forming a scepter just below the
termination.
From Mt Ida, Montgomery County, Arkansas.
Measures 23 cm by 28 cm by 22.4 cm in total size.
