Sir Dominic Mine, Flinders Range, South Australia
miniature, 3.8 x 3.7 x 3.0 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

Nice cluster of blocky crystals of malachite after azurite from a rarely seen location in South Australia. The 3.8cm cluster consists of malachite crystals which have a modeled green color, a chatoyant luster, and are about 1 cm across. Blades of azurite which have not been completely replaced by the malachite can also be observed on the cluster. Great location piece!



RH3-02 - Acanthite - $550
Guanajuato, Mexico
miniature, 3.4 x 1.8 x 1.2 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

Exquisite group of sharp metallic crystals to 7mm on matrix from the classic Mexican location for silver minerals, Guanajuanto. These crystals appear to have been deposited onto argentite crystals which formed earlier and were likely coated with some microcrystalline silver mineral. Some of the earlier deposited argentite has formed very interesting washboard crystal groups which give the piece an unusual look. Ex. Earl Calvert collection circa 1930s-1960s probably.



RH3-04 - Silver - $140 SOLD
Eleura Mine, Cobar, New South Wales, Australia
miniature, 3.2 x 1.9 x 1.1 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

Interesting group of silver wires up to 2.2cm long. The wires have a bright metallic luster and have small crystal growths along the sides. These silver specimens are very difficult to find at shows today and would make an excellent addition to any silver suite.



RH3-05 - Clinoclase with neat old Smithsonian label - $150
Mammoth Mine, Tintic District, Utah
miniature, 5.3 x 3.2 x 2.8 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

Note the REALLY OLD Smithsonian label, older than any other Smithsonian label i have ever sene out there nad predating their standardized typed labels we see even by the late 1800s! Very old matrix clinoclase from the classic U.S. location for the species. The specimen consists of small vugs containing crystals to about 5mm. The piece comes with two historic labels. The first is from the Smithsonian Museum and is a hand written label. The second is a label from The Thurstons, mineral dealers from the 1940’s and 50’s.



RH3-06 - Libethenite - $450 SOLD
Libethen, Slovak Republic (TYPE LOCALITY)
small cabinet, 7.4 x 3.5 x 2.4 cm
ex.  Richard Hauck

Rich specimen of libethonite on a quartz matrix, from the type-local of Libethen, Hungary. The crystals are well-formed and have a deep green color, really classic in style! The crystals also have a very nice glassy luster. Another old classic mineral which not commonly seen available.



RH3-07 - Copper in Calcite - $450 SOLD
Keweenaw Peninsula, Michigan
miniature, 3.1 x 2.1 x 1.9 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

Small cluster of semi-transparent calcite crystals to 1.8cm, with bright shiny copper included within. The scalahedral calcite crystals are sharp and well-formed with no significant damage. Michigan calcites with copper came from several mines in the district, but almost all came out almost 100 years ago. Few clusters appaer on the market, with most specimens being singles. Also, this one is just plain pretty! This specimen comes with a label indicating the piece was purchased from a William Collins on June 3, 1935.



RH3-08 - Copper - $125
Keweenaw Peninsula, Michigan
miniature, 5.9 x 3.8 x 2.0 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

Another nice old specimen from the Michigan copper country. This is a very nice native copper specimen with very well-formed crystals to 1.5cm long. The specimen appears to have modified dodecahedron and spinel-law twinned crystals. These copper specimens from Michigan are old, with most mines having closed prior to 1930’s.



RH3-09 - Algodonite - $150
Calumet, Michigan
miniature, 5.1 x 4.4 x 3.6 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

This is an extremely heavy copper species, being mostly copper. Even though it is not crystalline, it is a rare mineral species and this is a rich piece. The color is very much like that of crystallized copper, with a good patina.



RH3-10 - Embolite (now Chlorargyrite) from 1902 - $400
Silver King Mine, San Bernardino Co., California
small cabinet, 5.2 x 5.0 x 3.3 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

This, silver chloride, is a rare mineral species from places like Broken Hill, NSW, Australia. From the USA and in particular, California, it is rarer still. I have only ever seen a few out there for sale. This nodule has on one surface a sparkling druse of light brown to cocoa colored microcrystals. Discovered in 1902 and an important historical and locality specimen!



RH3-11 - Silver (ex. George Vaux Collection) - $1200
Zacatecas, Mexico
cabinet, 9.6 x 5.0 x 2.0 cm
ex.  Richard Hauck

CLICK HERE FOR LARGER IMAGE:

This specimen, a true oldtimer, is a solid mass of vein silver with minor associated copper on the back side. It was first brought to the states in 1890 by top US dealer AE Foote and it then went to of one of America’s greatest collectors, George Vaux (and retains his label as you see, with date on back). This is a VERY RICH AND HEFTY SILVER SPECIMEN for the locale , by old or modern standards!
