combination of cherry-red Rhodochrosite rhombs set among yellow Calcites and
purple Fluorite
with Quartz!
This incredible plate of eye candy is from the new workings at the Sweet Home

color and radiance that the Sweet Home Mine is
renowned for.
The large rhomb at top measures 3 cm in size. It sits surrounded by one of the
most impressive arrangements of yellow

A beautiful combination to say the least. This fine
Fluorite has a rich, bright golden coloration with
lavender zoning on many of the gemmy cubes. It surrounds a large Sphalerite in the center
and hosts
a smaller Sphalerite crystal near the top. The larger Sphalerite is accenting by doubly
terminated,
light yellow Calcite crystals. In very good condition overall with only trimming edge
contacting.
From the Ozark-Mahoning Mine, Cave-In-Rock Sub-District,

Extremely rare specimen featuring
iridecent Covellite crystals with Anglesite from Tsumeb!
I can count the number of Tsumeb Covellite specimens I've seen on one hand and
this is one
of the most impressive. The crystals are small which is normal for Tsumeb but
they are very
iridescent as displayed in the close up photo above. Scattered about the matrix
with the fine
Covellites are Anglesite crystals, glassy and mostly transparent. I don't know
when I'll come
across another Covellite for this famous locality so this represents a rare
opportunity for all
collectors. Mindat.org only has three examples of Covellite out of over 5600
Tsumeb pictures.
From the Tsumeb Mine, Tsumeb,

Aesthetic specimen featuring Native
Copper crystals sitting atop matrix!
This is a borderline large cabinet sized
specimen and it is incredibly attractive in both form and color!
The specimen is very crystalline and the majority of the surfaces are reddish in color,
indicating the
presence of micro-Cuprite. I love the way the Native Copper climbs the matrix and rises
upwards above
it near the center point. The overall visual impact is striking and very sculptural. The
fine coating of
Cuprite also means the color will remain constant and remain reddish-brown. This is a
specimen that
could actually be displayed from either side. If you turn the specimen around, you have
the appearance
of Native Copper crystals perched atop matrix. I prefer the side shown in the photograph
however.

Knarly old tree-like specimen of
Native Wire Silver with Acanthite and rainbow iridescence!
I was struck by this Silver which has so much character and arborescent form
that it's absolutely
beautiful. It reminds most, including myself, of an old sea spray aged Bonsai
Tree growing on a
rocky cliff or outcrop alongside the ocean. Rainbow colored iridescence
highlights the thickest wire
rising up from the left side of the matrix. This is a Silver collector's delight
and one of my favorites.

Very rare combination featuring
Argentite ps. after Galena with Realgar and Xanthoconite crystals on Barite!
Xanthoconite is a rare Silver Arsenic Sulfide (Ag3AsS3).
These rare specimens came to market years ago and
only a few good ones were available at that time. They've long since disappeared and I
haven't seen one in
almost a decade. The Xanthoconite can be seen scattered about atop the Barite blades near
the Argentite
which has completely pseudomorphed and taken on the habit of the Galena cubes. Red
Proustite crystals
are also present on this unique Silver specimen, displaying a close association with the
Xanthoconite.

Very rare

Wire Silver specimens from the Cobalt Mining District are very rare and
specimens featuring wires of this size
and width are almost never seen in the marketplace. These wires are most like
Silver ropes, measuring 1.2 cm

surfaces and both wires curl into what
almost looks like ramshorn tips. I was stunned to come across this specimen and
quickly acquired it for the website.

specimen of Native Wire Silver atop a matrix of massive Silver!

The wires that stand upwards are more like knarled ropes and they are all
very stable. There has
been some professional stablization done to add additional strength to the
wires. In excellent shape.
