Beautiful yellow plate of Botryoidal Mimetite on matrix!
A lovely plate with just a touch of orange in certain portions of the clean, mostly yellow surfaces.
A tiny sprinkling of Calcite crystals add a good amount of sparkle. The matrix is a thin one which
removes the bulkiness often seen with these specimens. The upright presentation is very nice.
From the San Pedro Corralitos Mine, Chihuahua, Mexico.
Measures 8.8 cm by 7.2 cm in size.
Comes with a custom made, engraved display base
Price $3500

Gorgeous rhombs of Rhodochrosite on Tetrahedrite with needle Quartz!
This specimen is as close to true perfection as you can get in a miniature sized Rhodochrosite
from the Sweet Home Mine. The rhombs are of the deepest color with glassy, uncontacted
faces and an incredible gemminess all the way down to the matrix. The backing is a dark
Tetrahedrite which further enhances the rich color. Quartz needles and Chalcopyrite are
also present on this fine specimen. Helmut Bruckner cherry picked this piece from hundreds
to be his own collection piece and it's very easy to see why. A specimen that is truely dazzling!
From the Octahedron Pocket, Mini King Raise, Sweet Home Mine, Alma, Colorado.
Measures 5.2 cm by 4.2 cm by 2.3 cm in size.

Brilliant and lustrous specimen of crystalline Native Gold atop Quartz matrix!

Fine crystals of Azurite and Malachite ps after Azurite on Malachite!
One of the better crystalline specimens I've seen from Morenci in quite some time.
The Azurite crystals are sharp and lustrous and the Malachite is pristine and very
chatoyant! No damage to speak of and the specimen displays very aesthetically atop the
Malachite matrix with a stacked crystal display. The appearance remind me of Bisbee.
From the Morenci Mine, Morenci, Greenlee County, Arizona.
Measures 9.2 cm by 5 cm in size.
Price $4850

RARE!! Scarce specimen of Köttigite crystal sprays on Limonite!
Köttigite is a Zinc Arsenate Hydrate and quality specimens like this one rarely appear at the
shows. This small cab plate of Limonite had not one but several separate sprays of the greenish-
blue mineral and all were in excellent condition thanks to the protective ridge along the left edge
of the matrix. The crystals are acicular, with the largest spray measures a full inch across (2.5 cm)!
Note: There is a 3 cm spray on the backside but it does have a slight contact.
From the Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico.
Measures 8.5 cm by 6.4 cm in size.

Classic specimen of North Carolina Native Gold in Chloritic Slate matrix!
I love finding old specimens like this. This large plate has a good amount of color atop the slate surfaces
and dates back to the original Gold Rush of North Carolina, the second Gold Rush in the United States
(Virginia was the first). This Gold Rush was also the reason a mint was established in Charlotte in the 1830's.
The surfaces of the specimen are Schistic in nature and exhibit the normal sparkling reflectivity under
lighting. It is the amount of yellow Gold atop the slate that drew my attention to the piece and the specimen
is very rich with a wide coverage of the precious metal. The original label is intact and dates the piece to
the 1840's when F. A. Genth spent a year working as superintendant at a silver mine in North Carolina.
The link attached to his name offers a complete biography on this collector. The item number on the
second label from the Academy of Natural Sciences of Philadelphia suggest this was a very early addition
to their enormous collection. They kept record of the provenance in the lower left corner of their label .
From the old Steele Mine, Ophir, Montgomery County, North Carolina.
Measures 10.4 cm by 17 cm by 4 cm in total size.

Beautiful specimen featuring blades of Orange Calcite on Quartz points!
Look closely and you'll notice that the Quartz on the far left is also orange! The top portion
of that Quartz crystal is included by the same material which gives the Calcite its orange
coloration - most likely Hematite. In excellent condition with full terminations and blades.
From the Messina Mine, Messina District, Limpopo Province, South Africa.
Measures 5.3 cm by 6.2 cm in size.

Dramatic, almost sculptural specimen of Stibnite crystals in Calcite matrix!
A very aesthetic Italian Stibnite which is both 3-dimensional and balanced. The Stibnites
are in very good condition with only some minor incompleteness here and there. All are
lustrous against the glossy white Calcite surfaces. The specimen was obviously etched to
expose the Stibnite and the preparer did a wonderful job of created a specimen with a lot
of eye appeal. I love the way the top looks like an ocean wave rising above the crystals.
From Montauto, Manciano, Grosseto Province, Tuscany, Italy.
Measures 6.2 cm by 8.4 cm by 7.4 cm in total size.
Price $1250

Interesting specimen featuring greenish-brown Embolite crystals with Goethite and Cerussite!
Chlorargyrite is the mineral known as "Horn Silver". It was once misunderstood by miners
until they had it assayed and discovered it was Silver Chloride and very rich. Embolite is
a variety of Chlorargyrite which adds some Bromian into the molecular mix and is also
known as Bromian Chlorargyrite. This specimen is covered with the waxy-brown crystals
which are accented by iridescent (bluish-lavender) Goethite and tiny twinned Cerussites!
I haven't seen this combination of minerals from the Broken Hill before and it's very nice.
From the Broken Hill Proprietary Mine, Broken Hill, Yancowinna Co., New South Wales, Australia.
Circa 1950's - Measures 9.5 cm by 7.4 cm by 5.5 cm in total size.
Price $2500

Rare combination of Azurite crystal balls clustered on Limonite with Selenite crystals!
I rarely find Azurite and Selenite specimens from Arizona and this may be the first I've found
from Morenci. I count five full sized Selenite blades and a few smaller Selenites here and there.
All come to a slanted termination. The Azurite balls are in good condition with undamaged
surfaces and loads of luster and sparkle. Only those along the trimming edge are incomplete.
From the Morenci Mine, Morenci, Greenlee County, Arizona.
Measures 9.5 cm by 8.5 cm by 6.2 cm in total size.
Price $1850
