the Richard Hauck Collection
RH1-39 - Dioptase, Cerussite, Wulfenite - AUS$ 163 SOLD Mammoth Mine, Tiger, Arizona, USA small cabinet, 6.6 x 3.8 x 3.3 cm ex. Richard Hauck
This oldtimer is an example of the species combinations for which the Mammoth Mine was so famous. Drusy, emerald green, lustrous, translucent, dioptase is associated with acicular, lustrous crystals of cerussite, to 1.2 cm in length along with a few, orange, wulfenite crystals, to .5 cm across. In fact, the whole matrix is highly porous, giving a home to the various species.
RH1-41 - Tetrahedrite - AUS$ 103 SOLD Cavnic (Kapnik), Maramures , Romania small cabinet, 6.9 x 5.0 x 4.6 cm ex. Richard Hauck
This specimen was probably donated to Lafayette College in Pennsylvania by professor Art Montgomery, one of the top field collectors/ mineral dealers the U.S.A. has ever produced. The specimen features lustrous, mirror bright, equant, black crystals, to 1.5 cm across, along with colorless, lustrous quartz crystals, to .5 cm across.
RH1-42 - Adamite - AUS$ 1362 SOLD Ojuela Mine, Mapimi, Durango, Mexico small cabinet, 8.5 x 4.9 x 2.6 cm ex. Richard Hauck
This is arguably the world’s finest locality for adamite and its wonderful variations. On this specimen, a limonite matrix is studded with discrete crystal fans, of highly lustrous, transparent, pastel yellow, adamite, to 1.5 cm across. The luster and color contrast is just spectacular. You lamost never see such bright adamite sprays isolated on the matrix, as opposed to grown solidly together! A fine old specimen, worthy of any collection
RH1-45 - Azurite with Malachite - AUS$ 2615 SOLD Tsumeb, Namibia small cabinet, 7.0 x 4.0 x 2.7 cm ex. Richard Hauck
This is a classic, large, lustrous, spear-point of deep navy blue azurite. The lower portion of the crystal has actually begun its long, inexorable, journey of becoming pseudomorphed by velvety, green, chatoyant malachite. The contrast is beautiful! The size and quality of this specimen from the now closed Tsumeb, leads me to believe that this specimen predated WWII. It is a ridiculously large crystal for the price, with a very fine, broad, textbook termination.
RH1-46 - Hematite - AUS$ 163 Congonhas di Campo, Minas Gerais, Brazil miniature, 3.7 x 3.0 x 2.5 cm ex. Richard Hauck
This is a complete, mirror bright, well formed cluster of hematite crystals. The longest crystal is 3.0 cm in length. Minor damage around the periphery is insignificant in context, really. It is a very dramatic piece, with crystals I want to call pseudocubic, that are possibly twinned.
RH1-48 - Witherite - AUS$ 272 Minerva Mine, Cave-in-Rock, Hardin County, Illinois, USA miniature, 4.2 x 4.1 x 2.3 cm ex. Richard Hauck
Most witherite specimens in the market exhibit a long prismatic form ending in a pinacoid. This complete crystal is short prismatic and the pinacoid is much broader. It is lustrous, translucent, and has a pleasing, pastel tan coloration. VERY FINE miniature for this now defunct locality, of one of its rare minerals
RH1-56 - Talc pseudo after Quartz - AUS$ 2124 Specksteingrube, Goepfersgrun, Fichtelgebirge, Bavaria, Germany small cabinet, 6.8 x 6.2 x 3.6 cm ex. Richard Hauck
This is one of those esoteric mineral specimens that defy logic. How can the softest mineral known totally replace one of the hardest? Nevertheless, this is a superb example of talc after quartz, from the classic and only locality we have seen it. These date to the 1800s and have long been staples in any fine european collection. Today, they are almost unavailable and rarely seen for sale anywhere. To me, they are one of the most desirable of all pseudos for the intellectual and historical value of the specimens. What were once clearly well formed, quartz crystals, to 2.5 cm in length, have been totally altered by tan colored talc. The large crystal here of about an inch is large for the occurrence and is the largest I have seen for sale in some time. The label indicates an early 1900s sale by Ward's.
RH1-57 - Acanthite after Argentite - AUS$ 218 SOLD Guanajuato, Mexico small cabinet, 9.2 x 5.2 x 4.1 cm ex. Richard Hauck
Battleship gray, lustrous, modified, crystals of acanthite after argentite, to.3 cm across, abound along with a quartz druse on matrix. Guanajuato is a noted locality for this pseudomorph.
RH1-59 - Azurite - AUS$ 218 SOLD Bisbee, Cochise Co., Arizona, USA small cabinet, 6.9 x 5.8 x 3.8 cm ex. Richard Hauck
Equant, deep blue, some with neon highlights, lustrous, azurite crystals, to .7 cm across, are nestled in a matrix vug along with minor malachite. BETTER IN PERSON than pics, and so cheap!
RH1-61 - Malachite pseudo after Azurite - AUS$ 218 Campbell Shaft, Bisbee, Cochise Co., Arizona, USA small cabinet, 7.0 x 4.6 x 3.1 cm ex. Richard Hauck
This specimen clearly exhibits the external form of azurite which have been replaced by malachite. The largest crystal exceeds 1.5 cm in length. These sharp, matrixbound pseudos are very collectible and rare today, having been found twice before in the early 1900s and in the 1960s
RH1-62 - Tetrahedrite and Quartz - AUS$ 136 SOLD Bingham, Utah, USA miniature, 4.0 x 2.8 x 2.2 cm ex. Richard Hauck
The defunct Bingham open pit, a huge disseminated deposit, was never known for crystallized specimens. Therefore, this specimen of bright, dark gray, tetrahedrite crystals, to .3 cm across, nestled among colorless, lustrous, translucent quartz crystals, to .7 cm in length, is a rare specimen!
RH1-65 - bipyramidal Wulfenite - AUS$ 1035 Ahumada Mine, Los Lamentos, Chihuaha, Mexico small cabinet, 6.9 x 4.9 x 4.4 cm ex. Richard Hauck
Of all the wulfenite habits extant in Los Lamentos specimens, the rarest is the bi-pyramidal habit exhibited by this fine piece. Crystals to 1.0 cm abound on a limonite matrix. The lustrous crystals terminate in a caramel candy, orange-brown color. Aesthetic and important!
RH1-67 - Cuprite - AUS$ 436 SOLD Irish Mag Shaft, Bisbee, Cochise Co., Arizona, USA cabinet, 10.2 x 6.4 x 3.0 cm ex. Richard Hauck
Crystals of lustrous, dark red, cuprite, to .5 cm across, stud the matrix of this specimen. This is an extremely rich and large specimen for the locality, and rare in such calibre.
RH1-68 - Cobaltite - AUS$ 2179 SOLD Hakansboda, Vastmanland, Sweden thumbnail, 2.5 x 2.3 x 2.2 cm ex. Richard Hauck
This beautifully crystallized piece, formerly in the noted collection of Stig Adolfsson then went to the Bergskolan Filipstad, Sweden. Bergskolan is swedish for school of mining. Filipstad is a small city in the south of Langban with this famous school of mining. It is a fairly rare copper cobalt sulfarsenide. It features a mirror-bright luster, and a battleship gray color along with modified faces. It is complete all around, though with very minor edge wear here and there. Given the significance, I can live with that and consider any small wear trivial in context. Crystals of this size are considered HUGE for the species, and I have never seen such a large example for sale before and this is a museum quality rarity
RH02-02 - Cinnabar - AUS$ 490 SOLD Almaden, Spain small cabinet, 7.6 x 6.8 x 3.7 cm ex. Richard Hauck
Classic old specimen of cinnabar on matrix with deep red crystals up to 8mm. THESE ARE VERY LARGE FOR SPANISH CINNABAR, at least for what I have seen on the market. The crystals are slightly bruised but have an outstanding luster and color. The matrix is so rich in cinnabar that it appears mostly red in color. These Spanish cinnabars came out decades or more ago and are not commonly available. Some date back over 100 years. this is one of the showiest I have had to sell
