Extremely rare specimen of Phosphophyllite crystals on matrix from Germany!
This is an incredibly rare cluster of greenish-blue Phosphophyllites from the Type Locality at the Hagendorf North Pegmatite in Bavaria, Germany.
The lustrous and gemmy crystals are well-formed, measuring to .9 cm in size, and are nestled in a Mica and Quartz matrix. Phosphophyllite was
discovered in 1920, and this piece most certainly dates back to the early 1900's. Although not one of the famous Bolivian specimens, this is an
very important and classic specimen from the actual Type Locality! This is a rare opportunity for collectors. The Hagendorf Quarry closed in 1937.
From the Hagendorf North Pegmatite, Waidhaus, Upper Palatinate, Bavaria, Germany.
Measures 4.2 cm by 3.8 cm by 2.2 cm in total size.

This is a very rare specimen of crystalline Native Silver and Silver leaf on a matrix richly impregnated with Silver. Circa 1880's, it's from the famous
Silver King Mine in Arizona. The Silver has incredible luster, both bright and with excellent patina. The Silver King Mine was discovered in 1873
and was depleted by 1888. This small cab also has an equally rich history, having been in both the Gathenye and Schwethelm collections previously.
This is a fine piece for an Arizona and or Silver mineral collection. Specimens from this locality rarely become available so opportunity knock here!

Satiny lustrous cluster of coated Calcite crystals!
The Calcites are pointed and display very sharp, angular edges. I thought the specimen might be a cast when I first saw
it but it is solid on the bottom with a white base. This indicates that the very angular Calcite crystals are actually bright
white beneath the golden-tan druse Calcite coating seen on the exterior. In excellent shape with full, complete terminations.

Amazing specimen featuring Native Copper pseudomorphing and replacing an old piece of mining timber!
This is the most impressive Copper replacing of wood that I've ever seen. At 20 cm in total length, it's also
the largest piece of  Copper replaced wood that I've ever offered on the website. This specimen is heavily
pseudomorphed down it's entire length as is quite obvious from the front and back pictures above. Some of
the original wood is still hanging on, giving the specimen further stability but this is one fine looking pseudo.

Impressive specimen featuring stacked crystal cubes of Halite from Poland!
I love these classic Halite specimens and this is the largest stacked cube pillar that I've seen in a long
time. The bottom cubes are colored brown by Hematite coating and as you move up the pillar towards
the top, the Halite cubes become clearer and translucent. You can still see the Hematite inclusions but they
become more of an internal phantom near the top. Lustrous and glassy, the crystal surfaces are all pristine.

Rare specimen of Quartz var. Amethyst crystals from Australia!
Rarely do I encounted a specimen of Amethyst from Australia and this specimen is a classic
cluster of seven crystals from the famous Wyloo Station locality which is one of the few areas
in Western Australia where Amethyst can be found. This specimen dates back several decades
and displays highly glassy faces and complete tips with barely a contact anywhere. There is some
obvious phantoming just beneath the lustrous surfaces. A lovely specimen that displays very well.
Locality: The Great Australian Amethyst Mine, Wyloo Station, Ashburton Shire, Western Australia, Australia.

Sparkling specimen featuring bluish-green Cuprian Adamite crystals on matrix!
This old timer dates back to the 1890's when it was offered by famed dealer George L. English. His original label
is included with the specimen. The specimen is very attractive with little in the way of contacts which is remarkable
considering its age. The crystals are small but their number makes up for this. They cover nearly every part of the
matrix with glassy crystal clusters. In excellent condition, this specimen is a true classic in every sense of the word.

Beautiful crystals of bi-colored Fluorite on matrix!
Vivid purples and greens color these Fluorite cubes which climb atop one another up the matrix. This is a
rare locality I have not previously offered and was one of the best specimens from the small collection. The
largest Fluorite cube measures 3.6 cm in size and all exhibit a strange chatoyance, almost like Labradorite
with a luminescence just beneath the crystal faces. Definately one of the most unusual Fluorites I've seen.

Cobalt rarity! Native Silver wires on Quartz in matrix!
Wires of Native Silver are extremely rare from the Cobalt Region and I've only
seen a handful of specimens in the past decade or two. These wires are popping out
from the Quartz seam that runs between the layers of matrix and wires are visible on
both sides of the specimen. The weight of this piece is quite heavy, indicating a large
amount of Silver in running through the Quartz. There are wires present on both sides.
