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.

Scarce and very impressive specimen of Spinel Twin Galena crystals with golden Fluorite!
This fine specimen is among the best Illinois Galena specimens I've offered on the website and I believe
it is also the first with golden Fluorite. All the others were associated with either purple or blue Fluorite.
The Galena cubes climb atop one another, forming an aesthetic towering structure of twinned crystals
which is interspersed with Fluorite cubes. The Galenas are bright and lustrous and contacts are minimal.

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.

Exceptional specimen of sharp, lustrous twinned crystals of Galena on matrix from Tsumeb!
This would easily rank as one of the finest Tsumeb Galena specimens I've seen recently.
The crystals are sharp and well defined, measuring to 1.6 cm in size. The surfaces have a
shiny luster and there is a slight reddish iridescence. Galenas of this quality from Tsmeb are
incredibly rare and the specimen is so high quality that it looks more like something you'd
find in the Tri-State Region than a mine in Namibia. In excellent condition with no detractions.

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.

Aethetic "rabbit ears" Calcite crystals on matrix with smaller Calcites!
This is a unique specimen from the famous Charcas locality and I've not seen another one like it
in two decades worth of mineral shows. On either side of the matrix are elongated, tabular-like crystals
of white Calcite measuring close to 7.5 cm and 8 cm in size. While the Calcite on the right is glassy and
translucent, the Calcite on the left is included by white poker-chip style Calcite crystals, which by the way,
can also be seen near the upper middle portion between the "rabbit ears". This is an interesting specimen
to say the least and the combination of Calcite habits is eye catching. In excellent condition with few contacts.

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.

Very well crystallized specimen, displaying numerous well formed crystals of Native Silver branching our

Beautifully crystallized Native Copper "fan" on Native Copper crystals!
This specimen is somewhat unusual for the White Pine Mine which is usually known for its
wires and fine dendrites. The top portion is an impressive crystalline fan that can be displayed
from either the front or back sides. The fan sits atop a more typical dendritic crystal formation at
the bottom and I love the visual impact of a large fan-like arrangement of crystals atop a smaller
dendritic growth. This is the way the specimen is displayed on its acrylic base as well. The surfaces
are lustrous and the crystallization is sharp and distinctive. A lovely antique patina covers all surfaces
and also allows the reddish color to peak through between the crystal faces. This is a great display piece.
