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
and this specimen is one of the finest Rhodochrosites from there that I've found in years.

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

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
dozens of translucent, stacked Calcite crystals which formed scalendohedral-like pillars

combination of Aqua-tipped Heliodor crystals on green Fluorite and Schorl Tourmaline!
I've sold a few of these scarce Beryl specimens over the last decade but this is the first
of Aqua-Heliodor crystals on green Fluorite that I've offered on the website! The crystals
in all directions atop the Fluorite at their base and Schorl Tourmaline frames the
specimen at both
the left and right edges. This is definately an eye catcher and one that is in excellent

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

Colorful combination of blue Azurite crystal
balls on green Malachite matrix!
These are some of the most attractive combos but I rarely see them anymore.
The blue Azurite balls are textured and contrast beautifully atop the Malachite.

Large lustrous Galena cube with yellow
Calcite crystals on matrix!
I love this specimen. The cube is super lustrous with mirror-bright faces on all sides
and measures 10 cm in size across the corners. It is complete and uncontacted on every
face and is accented by several yellow Calcite crystals atop the right side face, with a
them being doubly terminated. This is a specimen with presence and a very impressive

Pristine crystal of white coated Smoky
Quartz with a purple Amethyst scepter!
This is a great looking specimen and the Amethyst scepter appears to be doubly terminated
which is somewhat unique. The color is a deep grape-jelly purple with good gemminess at
top. The contrast between the purple and white surfaces is beautiful. In excellent

specimen of Vanadinite crystals in cluster!
Impressive specimen featuring reddish-orange
Vanadinite crystals measuring to over 1.3 cm in size!

that is this good.

rich specimen featuring a seam filled with and covered by numerous leaves of Native
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
