Item #A1

Exceptional miniature of Native Silver wires rising up atop Calcite matrix!
Silvers from the famous Kongsberg Mine just look different. They have class and presence
and the finest examples are always set atop white Calcite.... Like this 5 cm specimen which
features twisting wires and a brilliant surface luster. The two largest wires rise upwards like
Viking horns and the entire specimen is covered with thick Silver wires. Aesthetic and classic!
From the Kongsberg Silver Mining District, Svene, Flesberg, Buskerud, Norway.

Item #A2

Super bright and lustrous Native Silver after Allargentum and Dyscrasite on Calcite!
A dazzling specimen which is completely crystalline and extremely aesthetic. I nicknamed it "The Scorpion" due to its
interesting shape which I think resembles the claws and tail of a scorpion. The specimen can be displayed from either
side and displays the sharp crystals on both the front and back. The structure is dendritic which well formed crystals at
the ends and forming a good portion of the dendrite. The stark white Calcite and green matrix adds the perfect backdrop.

Item #A3

Stunning specimen of crystalline Native Gold sitting high atop Quartz matrix!
This piece reminds me of the famous bonsai tree on mountain top pictures. It is completely
crystalline and the close up photo displays the sharpness of the structure. It is essentially
dendritic in nature with individual crystals at the periphery and some of the dendrites appear
to be spinel-twins! The surfaces are bright and incredibly lustrous, with the entire crystalline
structure measuring over 3 cm in height. Below that, the Gold can be seen traveling its way
through the white Quartz matrix so there's much more Gold in this piece that what is shown.

Both Silver minerals sit atop a matrix of Quartz with Quartz crystal sprays.
The Acanthite crystals are so incredibly sharp and lustrous that at first glance, one
might not even notice the small "ram's horn" Silver located on the far right side of
the specimen! Acanthite and Silver combos from Mexico are rarely seen at the shows.

Item #A5

Extraordinarily rich and quite rare specimen of Native Gold on Quartz from the Vulture Mine!
This specimen is from the Vulture Mine which is located in the ghost town of Vulture City, just outside
the town of Wickenburg, Arizona. I've seen a handful of Native Golds from this old locality over the past
decade but I would have to say this is by far the richest. It's covered with seams of brilliant Gold on both
the front and back and even has a crudely crystalline structure in some areas atop the Quartz matrix.

Tucson2014-1GoldOrientalMineCalifornia7cm.jpg (211623 bytes)
Item #A12

Exceptional and rare specimen of Native Leaf Gold in white Quartz matrix!
This is a MAJOR Gold specimen and of a quality seldom seen from the Oriental Mine in
California. The Gold appears as brilliant layers of leaf Gold with crystals present along
the edges of each seam. There are also flattened trigons apparent atop the surfaces of
the leaf Gold so you could actually say that the entire specimen is crystalline! The color
of the Gold is a super lustrous butter-yellow indicating a small Silver presence in the mix.
(Orange would indicate Copper). Specimens of Gold from the Oriental in this size range
are quite rare and specimens with this much Gold coverage are incredibly rare! This fine
specimen represents a unique opportunity for Gold collectors and mineral collectors alike!

Thi

Item #A15

Brilliant, super lustrous leaves of Native Gold on drusy covered matrix!
This is one of the finest Romanian Gold specimens it has been my pleasures to add to the website
in several years at least. The sparkling surface of Quartz covered host rock is beautifully graced by
bright golden leaves and dendrites which spread out from the middle and drape across the very top of
the specimen. The color is a much richer golden-yellow than what one normally sees from this locality,
indicating a higher purity. The surface luster is off the charts and the aesthetics speak for themselves.

An exceptional example of fine herringbone crystal formation, not from Batopilas, but from
the San Genaro Mine. Brilliant luster rolls across the fine crystalline dendrites on both front
and back with a 2+ cm spinel twin shooting across the very top. This is easily one of the most
attractive small miniatures that I've seen from the San Genaro Mine. In excellent condition.

Item #A21

Rare specimen of Acanthite crystals with Proustite on matrix!
This specimen is loaded with lustrous Acanthites and ruby-red Proustite crystals. I can't recall
seeing such a rich concentration on a single matrix before from Germany. The Acanthites are
sharp and raised up from the matrix. The largest triangular crystal in the close up photo measures
.7 cm in size. These crystals are surrounded by red Proustites and some are even partially covered
by them. The Proustites vary in size from a few mms to .5 cm. Overall the specimen is in excellent
shape with complete crystals and good aesthetics. A few of the Proustites are contacted but this is
pretty normal for Proustite specimens and it doesn't detract. You'd need a loupe to see the contacts.

Denver2015-164SilverCalumetandHeclaMineMichigan97mm.jpg (132689 bytes)
Item #A22

Exceptional specimen of Native Silver crystals, one atop the other, atop a Native Silver base!
This is an old classic specimen, dating back to the 1880's, and it comes from the same collection
my "Pine Tree on Copper" specimen came from. Both were preserved by the same miner over
130 years ago and remained in his family before being sold just recently. This specimen is pure
Silver with no Copper present, and is formed from numerous crystals measuring to 2 cm in size.
Even the base appears to be a crystal or crystals that were flattened somewhat by surrounding
matrix which has long since been removed. The specimen is highly lustrous and exhibits a gentle
antique greyish-golden patina. It's very sculptural with a beautiful form and even includes a natural
opening formed by touching crystals along the top left. This was easily one of the most impressive
Native Silvers at the show and is completely original. It also offers a lot of size for a reasonable price.

Old time specimen featuring lustrous leaf Gold nestled between white crystal points! There

in texture. I would date this specimen to the mid 1850's to as possibly as late as 1890. The old

California are visible. Numerous Quartz crystals form the host matrix and some are terminated!

Item #A24

Classic and quite rare specimen of Native Gold on matrix from Goldfield, Nevada!
This is a historical specimen from a major early mining period of Nevada's history. Goldfield
was mostly known for its Gold mines while Tonopah to the north was famous for its Silver deposits.
The two towns had their heyday around the same time period (1900-1920's) and are today still holding
on although Tonopah has done somewhat better thanks to a nearby military base. The district is very
historical and full of old mines. It's also one of my favorite areas to visit when I'm in the area. This
specimen features a rich scattering of Native Gold atop the front and back of the stained Quartz matrix.

Item #A27

Historical and very rare specimen of Native Gold with Silver Sulfides on matrix from Nevada!
This cabinet sized plate is an amazing example of American and Nevada mining history. It's from
the old mining district of Tonopah, Nevada which was the home to a huge Silver mining boom in the
early 1900's. While Silver was the main ore discovered in Tonopah, there were also gold deposits
although most were a bit further south in Goldfield. This specimen displays a large Rhyolitic volcanic
plate, naturally seamed, into which flowed Native Gold. The Gold cooled to form micro-crystalline
clusters. The close up photos display the front and right edge of the specimen which is covered with
the brilliant precious metal. The Gold is mostly crystalline dendritic with some small trigons, leaves,
and mesh also present. Gray Silver Sulfide is also present in the matrix but the Gold is the main draw.
Specimens of this size with this much Gold coverage from Tonopah, Nevada are incredibly rare today.

Item #A30

Dramatic specimen featuring Native Copper crystals with Native Silver banding!
This is a tremendous halfbreed and definately one of the most attractive I've seen from the
White Pine Mine. It's almost completely crystalline and features Silver banding near the base,
just above the base, and at the midpoint of the "V". The color and luster shift is quite noticeable
and makes for great aesthetics. I see what appears to be a spinel-twin Copper crystal along the
right side of the upper branches and the Copper luster is evident through the reddish-brown patina.
From the White Pine Mine, White Pine, Ontonagon County, Michigan.
Measures 11 cm by 10.4 cm by 1.5 cm in total size.
Ex. Liebetrau Silver Collection
Comes with a custom made, labeled display base
