rhomb of Rhodochrosite sitting atop Quartz crystals!
It looks like a Sweet Home Rhodo but it's not. It's from the famous Pasto Bueno locale in

Unique and stunning specimen of Native Silver dendrites rising up from a Calcite crystal!
This is a White Pine Silver and it is the finest example I've ever seen from this classic
locality. To find
a matrix White Pine Silver is a rare thing. To find a matrix White Pine Silver with the
dendritic structure rising up from a Calcite like a Kongsberg specimen is AMAZING to say
The dendritic crystalline structure rising up from the matrix is sharp and distinctive and

lovely antique patina over santiny lustrous surfaces. In excellent condition with
exceptional eye appeal.

plate featuring Purple Fluorite cubes set against large, connected Galenas!
This is one of most unique Illinois Fluorites I've seen and I love the arrangement of the
Galena cubes in the background, forming a "mountain range" above the Fluorite
covered surface in the foreground. The Galenas are quite interesting in that they almost
like twinned crystals. There are three cubes in the cluster and they appear to be grown
at the edges, creating the unique mountain-like appearance. In excellent condition with
scattering of tiny contacts on some Fluorites. You'll be hard pressed to find a more

Classic Montana rarity featuring a Native
Wire Silver filled vug inside Amethyst, Pyrite, and Galena matrix!
This is a wonderful specimen from a seldom seen Montana locality. The matrix is a
beautiful mix of Quartz
with winding Amethyst seams and Pyrite crystals. Near the top, a Quartz lined vug opens up
a sizeable nest of Native Silver wires, which are in turn, host to smaller Acanthite
Acanthite (or Pyrargyrite) can be seen inside the vug alongside and behind the wires. This
is a the finest
cabinet sized specimen I've ever seen from this locality and it represents a very rare
opportunity for collectors.

flashy crystals of deep green Uvite Tourmaline in cluster with Quartz and Magnesite!
This beauty can be displayed from either side because the crystals are just as perfect and
glassy-lustrous on both the front and the back. There are no visible contacts but the
side displayed in the above photograph does have two small crystal-clear Quartz points
while the back side displays a scattering of Magnesite crystals among the green Uvites.

rarity! Fine crystals of Calcite on matrix from St. Andreasberg!
This locality was an old Silver Mining District in Germany but today all the mines are
since closed and reclaimed for the most part. I don't come across many fine Calcite plates
from this locality and all date back to the late 1800's or early 1900's. This plate

clear cubes of Fluorite perched atop brown Quartz crystals!
This is a lovely specimen with stark contrast between the completely colorless Fluorites
and the brown coated Quartz crystals. The brown coating appears to be a Calcite drusy
and it covers nearly every portion of the specimen's surface. The Fluorites measure up
to nearly 2.5 cm in size and are so clear that they look like glass. The cubes to the left
are so transparent that they display the Quartz matrix beneath. The cube to the far right
steps down due to matrix influence with a small cleave on the back side. It does not

impressive specimen of crystalline Native Copper growing upwards atop a Copper base!
This specimen is amazing. It's from the White Pine, the same locality as the exceptional

The seam is exposed on both sides and leaf Silver can be seen jutting out from the seam
entire length. This a specimen from the classic Cobalt Mining District and the weight is
impressive attesting to the density of Silver. Turning the specimen over, one can see
layers of Native Silver inside the Calcite seam along with some associated Acanthite and
crystals. I also see some rainbow iridescence atop the Native Silver. This specimen is
