perfect termination. It sits atop white Cleavelandite blades, surrounded by smaller, gemmier
green Tourmalines. In excellent condition with no detractions or visible damage to speak of.

MIN#TUCSON2020-59b NEW!

Fine crystals of Native Silver in cluster high atop Native Copper!
Wonderfully aesthetic specimen which is one of the most distinctive halfbreed specimens
I've ever seen from the old Michigan Copper Mining District. The crystals are sharp and
well formed as they branch out from the lustrous cluster at top. I actually nicknamed this
specimen the "Silver Eagle" because I can see an eagle sitting on a nest with wings formed
from the numerous Silver crystals. In excellent condition with a beautiful visual display.
From the Kearsarge Mine, Kearsarge, Houghton County, Michigan.
Measures 7 cm by 3.8 cm by 2.5 cm in total size.

Excellent example of an Illinois Galena specimen with surrounding Fluorite crystals!
This is easily one of the best Galena specimens I've seen from Illinois in terms of balance
and centering of crystals. It's a true work of natural art, with the largest cube in the middle
measuring 2.7 cm in size across the corners. It's surrounded by well over a dozen lustrous
Galenas and an accenting of small reddish-purple Fluorite crystals. In excellent condition.

MIN#TUCSON2020-62 Sold!

Gorgeous vug filled with radiating crystals of transparent blue Hemimorphite!
This is a lovely piece of the rarely seen Hemimorphite from the famous Skorpion Mine. The matrix vug
is filled with lustrous, gemmy, baby-blue colored radiating clusters of Hemimorphite on host rock matrix.
The concave structure of the matrix opening has done its job well and protected the crystals from contacting.
Also, the top Hemimorphite ceiling of the vug is translucent and allows light to penetrate into the vug interior.
Locality: Skorpion Mine, Rosh Pinah, Lüderitz District, Karas Region, Namibia.
Measures: 5.7 cm by 9.3 cm by 6.7 cm in total size.

MIN#TUCSON2020-64 Sold!

Scarce specimen of Realgar crystals in cluster with Picropharmacolite!
I can't stress enough how hard it is to find fine Realgar specimens in the marketplace.
They mostly disappeared over a decade ago and I rarely see them at the shows. This is
a superb small miniature with deep red Realgar crystals, all of which are in excellent condition.
White Picropharmacolite sprays can be seen around the periphery and these provide an aesthetic
contrast between the two minerals. In excellent condition with excellent color and no scuffing.
Locality: Jiepaiyu Mine (Shimen Mine), Shimen Co., Changde Pref., Hunan Prov., China.
Measures: 4.3 cm by 4.5 cm by 3 cm in total size.

Superb specimen of crystallized Gold var. Electrum specimen!
This entire specimen is composed of crystals in all shapes and sizes! There are even
some spinel-twins in the mix and thick wires that bend back towards the Quartz matrix.
The luster is excellent and the color suggests a Silver content of at least 30% or higher.
I love quality Electrums from Nevada and this is one of the finest I've seen from the show.
From the Round Mountain Mine, Round Mountain District, Nye County, Nevada.

Gemmy crystals of Native Sulfur from an old Roman locality on the Italian mainland!
These are scarce specimens and a locality I rarely see available for sale at the shows. The crystals
are beautifully formed and gemmy with smooth lustrous surfaces. With most of what you see from
Italy being from Sicily, a specimen from this mine would make a great addition to any collection.

Super aethetic specimen of Native Leaf Silver with Calcite and iridescent Safflorite clusters!
This classic specimen from the old Cobalt Mining District is one of my favorites from the show. The crystalline
leaf of pure Silver is so brilliant and lustrous as it rises up from a matrix of Calcite and is framed by the bluish-
purple iridescence of the Safflorite crystals. For me, this specimen is pure eye candy. It's also displayable from
both sides as the large Silver leaf is perfectly centered atop the middle of the hard matrix. Flashy and remarkable!
From the Cobalt Mining District, Cobalt-Gowganda Region, Timiskaming District, Ontario, Canada.
Measures 6.5 cm by 9.2 cm by 6.2 cm in total size.

Amazing stalactite Cave Calcite from Mexico!
This is one of the largest, most intricate, and most aesthetic Cave Calcite specimens I've ever seen.
It has been beautifully preserved and protected throughout the years and there is almost no contacting
on any of the surfaces. From the famous Santa Eulalia District, this centerpiece displays two distinct
forms of Calcite, one being a fine, elongated scalendohedral shaped crystal with numerous secondary
crystal points jutting out from the center, and the other a much thicker, golden colored stalactic shape
structure. The tips and major terminations are all complete and the specimen is in amazingly good shape!
Locality: Santa Eulalia Mining District, Aquiles Serdán Municipality, Chihuahua, Mexico.
Measures: 25 cm by 14.4 cm by 10 cm in total size.

Iron-Nickel (IAB) meteorite from the Campo del Cielo impact!
A large, impressive Meteorite from the epic fall with well formed regmaglypts and a satiny
lusterous surface! This was one of the finest specimens at the Tucson Show and is the largest
of the entire collection. It could be displayed well from either side and is completely covered
with a collection of superb regmaglypt impressions. The form is also excellent and well balanced.
Special Note: On January 1, 2008 Argentina implemented a new law prohibiting the exportation
of meteorites. When the available supply on the market is exhausted, obtaining a specimen
will become extremely difficult. Now is the time to obtain a meteorite for your collection.
Locality: Campo del Cielo impact at Formosa, Argentina - discovered in 1576.
Age is approximately 4000 years old.
Measures: 12.4 cm by 14.8 cm by 10.5 cm in total size.
Comes with a custom made, labeled display base

EXCEPTIONAL!! An amazing plate featuring a huge Apophyllite crystal with Calcite atop green Prehnite!
This is a a specimen the likes of which I've never seen before from Namibia. Apophyllite is not a common
mineral from this locality but it does appear as small crystals every now and then. I have never seen an
Apophyllite crystal of this size from the Goboboseb locale and there are no pictures of anything like this on
mindat.org. The Apophyllite crystal stands upright atop the Prehnite which display complete, glassy faces
on all sides and measures 3.5 cm in size. It sits next to a 2.6 cm Calcite and is surrounded by a brilliant
surface of super lustrous Prehnite crystals. I can't stress enough just how rare this specimen is. It rivals
the Apophyllites one would see from India which is remarkable for Goboboseb! In excellent condition.
From the Goboboseb Mts, Brandberg Area, Dâures, Erongo Region, Namibia.
Measures 7.8 cm by 7.7 cm by 12 cm in total size.

MIN#TUCSON2020-75 NEW!

Large, lustrous crystal of Acanthite ps after Argentite!
We acquired a collection of this very large, super lustrous Acanthite crystals while in Denver
and they are quite the sight to see. Most if not all display some hoppering indicating a very quick
formation as the Acanthite pseudomorphed the higher temperature Argentite. Exceptional crystal!
From Fresnillo de Gonzalez Echeverria (Fresnillo), Mun. de Fresnillo, Zacatecas, Mexico.
Measures 2.5 cm by 3.1 cm by 2 cm in total size.
