the Richard Hauck Collection
A NOTE ABOUT HISTORIC SPECIMEN LABELS:
RH3-01 - Malachite pseudo after Azurite - AUS$ 442 Sir Dominic Mine, Flinders Range, South Australia miniature, 3.8 x 3.7 x 3.0 cm ex. Richard Hauck
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 - AUS$ 608 Guanajuato, Mexico miniature, 3.4 x 1.8 x 1.2 cm ex. Richard Hauck
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 - AUS$ 155 SOLD Eleura Mine, Cobar, New South Wales, Australia miniature, 3.2 x 1.9 x 1.1 cm ex. Richard Hauck
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 - AUS$ 166 SOLD Mammoth Mine, Tintic District, Utah miniature, 5.3 x 3.2 x 2.8 cm ex. Richard Hauck
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 - AUS$ 498 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 - AUS$ 498 SOLD Keweenaw Peninsula, Michigan miniature, 3.1 x 2.1 x 1.9 cm ex. Richard Hauck
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 - AUS$ 138 Keweenaw Peninsula, Michigan miniature, 5.9 x 3.8 x 2.0 cm ex. Richard Hauck
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 - AUS$ 166 Calumet, Michigan miniature, 5.1 x 4.4 x 3.6 cm ex. Richard Hauck
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 - AUS$ 442 Silver King Mine, San Bernardino Co., California small cabinet, 5.2 x 5.0 x 3.3 cm ex. Richard Hauck
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) - AUS$ 1327 Zacatecas, Mexico cabinet, 9.6 x 5.0 x 2.0 cm ex. Richard Hauck
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!
RH3-12 - Bromargyrite - AUS$ 829 Broken Hill, NSW, Australia miniature, 4.7 x 3.9 x 3.5 cm ex. Richard Hauck
This mineral species, a rare silver bromide, reaches its zenith here at the Broken Hill Mine, NSW, Australia. Elongated, lustrous, translucent, green, crystals of bromargyrite to .7 cm in length, sit up on matrix. In some ways the bromargyrite crystals look like jelly beans. Classic and beautiful for this material!
RH3-13 - Copper pseudomorph after Aragonite - AUS$ 829 SOLD Corocoro, Bolivia miniature, 3.9 x 3.3 x 2.1 cm ex. Richard Hauck
Although its original external form is still obvious as being aragonite, it is very evident that the aragonite has been totally replaced by copper. This is a neat, unusual, specimen! These classic copper pseudos are seldom seen today on teh market and to me represent one of the most interesting pseudos of all out there, in that such a common carbonate as aragonite has been replaced by a native element.
RH3-14 - Silver - AUS$ 276 SOLD Molly Gibson Mine, Aspen, Colorado thumbnail, 2.8 x 2.5 x 1.1 cm ex. Richard Hauck
In the latter part of the 19th. century, this was one of Colorado’s more active silver mines. This specimen is composed of white, calcite and wires of silver, to .5 cm in length. When photographed in a closeup, this is a beautiful, thumbnail specimen.
RH3-15 - Proustite - AUS$ 221 SOLD St. Andreasberg, Saxony, Germany thumbnail, 2.9 x 2.5 x 1.6 cm ex. Richard Hauck
Although this is an old specimen, this "ruby silver" when backlit, still exhibits remnants of its deep, red, color. The primary crystal measures 1.5 cm across.
RH3-16 - Copper pseudo. after Azurite - AUS$ 940 SOLD Georgetown, Grant County, New Mexico miniature, 3.9 x 2.9 x 1.6 cm ex. Richard Hauck
I really like this pseudomorph of copper after azurite. The original form of azurite as a rosette is clearly evident. This piece has more form and aesthetics than most from there, as well as a superb patina . Also it is rather large for the material - most are 3 cm and smaller! Overall a historic and very interesting specimen.
