scalenohedral crystals of Rhodochrosite on Manganite matrix!
Gemmy crystals with a scattering of drusy accenting atop some tips, this
specimen is pure pizzazz!
I haven't offered many South African Rhodos over the years but this one caught
my eye the moment
I saw it! The crystals are in excellent shape with full terminations and glassy
faces that clearly show
the inner gemminess of each Rhodo! The drusy accents impart a brilliant sparkle
to the Rhodochrosite
crystals while the dark Manganite matrix adds a deep contrast. In excellent
condition with no detractions.
From the N'Chwaning Mines, Kuruman, Kalahari Manganese
Fields, Northern Cape Province, South Africa.
Measures 4.1 cm by 6.2 cm by 3.8 cm in total size.

Spectacular and incredibly
brilliant specimen of crystalline Native Gold on white Quartz matrix!
This is one of those very fine specmens that you come
across every now and then that simply amazes
and grabs your attention. It's a large miniature sized Gold which displays the
aesthetics and presense of
a much larger and much more expensive specimen. Quality crystalline Golds like
this one don't come
along very often, regardless of their size. This specimen is incredible lustrous
and is composed of crystals
from top to bottom. The color of the Gold is a rich, brilliant yellow and the
piece could be displayed from
either side as both are equally as crystalline and equally as attractive. One of
the finest Golds in Tucson!

Large gemmy cubes of lavender phantomed blue Fluorite atop one another!
The surfaces of this cluster are super lustrous and only serve to further
enhance the deep blue
coloration of the interiors which glow when exposed to even faint lighting. The
the cubes with a touch of lavender-purple and the surfaces are blemish-free. The
back side displays
stepped faces which is suggestive of a rehealing process. The luster atop the
faces is wet and intense.

Elegant specimen featuring gemmy
green Tourmalines with blue capped terminations on Quartz!
This is an amazing cluster, featuring half a dozen Tourmalines, all of
them super glassy and beautifully
striated with a rolling luster. Five of the Tourmalines display a vivid blue cap
termination above the
gemmy to translucent green lengths. The sixth Tourmaline is a rehealed
termination which displays the
faint beginnings of a blue cap which did not fully develop. The cluster of
Tourmalines sit atop the front
side of a Quartz crystal which serves as the host matrix.

Exceptional Native Leaf Silver with Safflorite and
Skutterudite from the Cobalt Mining District!
This is an amazing Silver - Easily one of the finest Cobalt specimens I've ever
seen and I acquired
it for the website the moment it was offered to me. Atop the white matrix you
have a beautiful display
of numerous lustrous Native Leaf Silvers, all standing upright, with grayish
Safflorite crystal clusters
and Skutterudite nestled between. The leaves average around 2 cm in size and the
visual display of
the specimen is very 3-dimensional. In excellent condition and very, very
impressive! The Castle Mine
is a Silver Mine just west of Cobalt which has produced since 1917. It produced
6.5 million ounces of
Silver and 300,000 lbs of Cobalt by the end of 1931. The mine opened and closed
again in the 1980's.
Mindat.org displays only a handful of photos for the locality with none being as
impressive as this one.

Exceptional cluster of Quartz var. Amethyst crystals in cluster!
Incredibly gemmy and deeply colored grape-jelly purple Amethyst crystals on a
small amount of matrix.
The color and glassy luster of these crystals is among the best I've seen from
Brandberg. The specimen
almost appears wet and the interiors glow in normal room lighting with internal
phantoms quite visible.

Lustrous and iridescent Siderite epimorphs after Calcite crystals from South
An amazing specimen, these are actually Siderite epimorphs of former Calcite
have dissolved and been replaced in totality. The Calcite crystal habit has been
but they are in actuality only shadows of their former selves in that they are
now hollow casts of
Siderite. The hollow casts are pristine and blemish free with a slight
iridescence atop the surfaces of
the largest crystal and a vibrant, rolling luster. I don't see these specimen
often and this is a great one!

specimen featuring a rich assemblage of fine Native Silver wires with Acanthite
This is one of the finest Silver wire specimens I've ever seen from the classic
locality of Guanajuato and
the eye appeal, luster, and flash of this specimen is dazzling. The matrix emits
a strong sparkle from
beneath the dozens and dozens of brilliant, twisting wires and an accenting of
grayish Acanthite adds
additional contrast to this very visually pleasing specimen. In excellent
condition, this is one of my favs!

rarity! A large lilac Apatite crystal sitting alongside a Beryl var. Aquamarine
Also with Albite and Muscovite, this is easily the finest Apatite-Beryl combo
specimen I've seen from Maine
and I don't know of any others that even come close. This specimen was acquired
privately back in 1969
by Richard Kosnar from Perham's Mineral Store which was located in West Paris,
Maine. The specimen
actually comes with the original bill of sale. The purplish Apatite crystal is
glassy lustrous and measures
2 cm in size. Its companion Aquamarine crystal measures a well matched 1.8 cm
and is also quite lustrous
with reflective surfaces. Both crystals are sharp with only trivial contacts.
The north side of the Aqua is
slightly irregular where it formed around a now missing Albite crystal. I can't
stress how incredibly rare
a combination of this calibre is from Maine pegmatites, especially one in this
condition and with the
aesthetical qualities of this very special, small cabinet sized specimen. In
excellent condition overall.

Quarry, East Mount Apatite District, Auburn, Androscoggin County, Maine.

featuring a perfect radial ball of Prehnite centered atop white Calcite xls!
Also with Quartz, this is a super aesthetic Prehnite specimen! Extremely
lustrous and perfectly
placed, this Prehnite crystal ball is complete all the way around. It measures 3
cm wide and is one
of the finest examples I've seen from this locality. I love the Calcite crystal
covered matrix that
contrasts so well with the vibrant green Prehnite. In excellent condition
and sits upright by itself.

Very impressive specimen of Native Gold on Quartz from Western Australia!
This is an super atractive specimen from down under, displaying crudely formed
crystals of brilliant
native Gold draped atop and throughout marbeled Quartz matrix. The photos above
display the specimen
from both the front and back sides. This is clearly a specimen that looks great
from all sides! The Gold
is richly colored, indicating a very high purity, and is clean of any iron
staining. Very lustrous and bright.
Western Australia, Australia.

specimen of Native Wire Silver on Calcite matrix from Kongsberg!
This is easily one of the most artistic looking Native Wire Silvers I've seen in
size range. A firm, study wire rises high above the left side of the white
Calcite matrix before
curling inwards at the very top. It's balanced on the right side by a smaller
but equally impressive
wire and a looping wire situated atop the Calcite in the very center. This wire
forms a complete
ring between the two vertical wires. All wires are strong and firmly attached to
the Calcite matrix.
From the Kongsberg Silver Mining District, Svene, Flesberg,
Measures 5.5 cm by 2.5 cm by 1.6 cm in total size.

Exceptional specimen featuring a large, Marcasite phantomed Calcite crystal on
This lovely specimen is from a Calcite locality not often seen at the shows -
The Conco Mine in upstate
Illinois. Specimens are quite scarce and Calcites of this size are almost
impossible to find. This golden-
yellow crystal measures just shy of 8 cm in size and is pristine with a
sparkling inclusion of Marcasite
and Pyrite just beneath the lustrous faces. Near the interior of the crystal is
a very visible phantom
caused by an earlier termination being coated by Marcasite micro-crystals.
Flashy with no contacts.

most appealing Copper-Silver combos I've seen in the miniature size range in the
past two decades.

Exceptional halfbreed of dendritic
Native Copper partially coated by
This specimen is from the famous White Pine Mine and the finest Coppers and
there have an incredible dendritic form of growth. This one however features
crystals of both minerals together on the same large specimen. The display is
the luster flows freely over both the white Silver surfaces and reddish-brown
The Silver near the top becomes so heavy in areas that it almost appears to be
the Copper crystals but I still think it may just be a secondary coating.
Regardless, the visual
impact and eye appeal is incredible. Can be displayed from either side but this
is my favorite.

Great looking specimen of Galena cubes stacked atop Dolomite covered matrix with
One of my favorite specimens from Tucson, this cabinet display piece features
three large mirror-bright
Galena cubes perched atop one another. The largest of these measures 6.5 cm
across the corners. At the
top are a couple of frosted Calcite crystals and along the base and bottom side
are numerous golden Calcites.
The Galenas are complete with a stepped back side formation. In wonderful
condition with loads of eye appeal.

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.
