Q-489  botryoidal Amethyst  RESERVED

Mamuju Area, Sulawesi Barat Province, Sulawesi, Indonesia

9.3 x 3.5 x 3 cm

A fine sculptural aggregate of botryoidal Amethyst from the 2016 find in Indonesia. These spheres have a vivid purple-lilac color with some sparkle. The spheres on this specimen measure up to 5mm, which is a little larger than average for these specimens. Originally marketed as Agate or Chalcedony, these have been recently shown to be Amethyst. Botryoidal Amethyst is quite rare worldwide.

Wushan Spessartine Mine, Tongbei, Yunxiao County, Zhangzhou, Fujian, China

12.6 x 8.7 x 4.7 cm

A rather large Garnet specimen. These Garnets have a good luster. Another plus is the striking orange color, much like the famous Spessartine Garnets from the world famous Little Three mine in Ramona, California.

12.3 x 11.7 x 7.4 cm

This specimen features many spheres of the Copper carbonate mineral Rosasite on a matrix of pink-colored Dolomite crystals. Some of the Rosasite spheres and some of the Dolomite crystals have a thin coating of clear Gypsum. There are also several amorphous masses of green-colored Malachite present on this specimen.

C-282  Copper  $220

Arcadian Mine, Ripley, Houghton County, MI

10.5 x 6.2 x 4.3 cm

Here we have a specimen of coarsely crystallized Copper on perfectly proportioned matrix. This specimen has a rich patina, both on the Copper itself and the matrix. This specimen is a real old-timer. The original Arcadian Mining Co. was organized in 1864, then reorganized as the Arcadian Copper Company in 1898 after the consolidation of the Edwards, Douglas, Concord, Highland, St. Mary's, and Arcadian mines. The mine closed permanently in 1903. Two more attempts were made at mining in the location in 1909 and 1920, but both were unsuccessful.

C-283  Cristobalite in Obsidian  RESERVED

Coso Hot Springs Deposit, Coso Hot Springs, Coso Mining District, Inyo County, CA

12.3 x 9.5 x 3.6 cm

Hemispherical gray-white lithophysae filling gas cavities in an Obsidian matrix. The “eyes” or spheres of high temperature Cristobalite (SiO2) are the result of devitrification, or loss of silica from the Obsidian. When lit properly the Cristobalite sparkles. The hot springs are part of the geothermal activity of the Coso Volcanic Field located within the boundaries of the Naval Air Weapons Station China Lake and collecting is no longer permitted.

B-230  Brucite  $60
Ex R. Trimingham, J. Parnau Collections

Sierra Magnesite Mine, Gabbs, Gabbs Mining District, Paradise Range, Nye County, NV

9.7 x 6.3 x 4.3 cm

A large specimen of off-white-colored, massive Brucite with platy, blue-green colored crystals of Brucite.  The “main” event of this specimen is a sharp, translucent and well-formed 1.8 centimeter crystal of Brucite. Brucite is a magnesium hydroxide. The label notes that this specimen was in the collection of John Parnau (1906-1990) of Campbell, CA, after whom the secondary Cu-sulphate-arsenate mineral Parnauite is named. This specimen was obtained by Mr. Trimingham in 1991 for $125.00 and that he considered it a very fine specimen. I agree.

C-284  Corundum variety Sapphire  $50  

Beitbridge District, Matabeleland South, Zimbabwe

6.8 x 4.7 x 3.1 cm

A blue-gray crystal of Sapphire with a jacket of Biotite. This crystal has some lustre and is complete all around. I am told that the mine collapsed some time ago and there are no plans to re-open it.

If, like me, you are a fan of Corundum; check out this website: The Corunduminium

C-285  Cryptomelane  RESERVED

Reaphook Hill, Martins Well, South Flinders Ranges, South Australia, Australia

10.1 x 3.2 x 1.6 cm

A blistered spire of the manganese mineral, Cryptomelane. This mineral is usually not this good-looking and is not well represented in most mineral collections. Reaphook Hill was worked for a time for mineral specimens (mostly Scholzite) in the 1970's but nothing has been done there since.

Potosí Mine, Francisco Portillo, West Camp, Santa Eulalia District
Municipio Aquiles Serdán, Chihuahua, Mexico

9.2 x 5.6 x 4.2 cm

A glassy, zoned and double terminated Quartz crystal on a matrix of smaller Quartz crystals. The zoning appears to be cause by inclusions of the mineral Goethite. There is no damage to this specimen.

G-155  Andradite Garnet  RESERVED

Sinerechenskoe Skarn Occurrence, Primorsky Krai, Russia

15.3 x 6.8 x 7.2 cm

This specimen consists of many well-developed, glassy and transparent crystals of  Andradite.  The crystals on this specimen range in color from cinnamon to yellow-brown. In this photo many of the crystals appear to be darker than they really are because of the fact that the specimen is one mass of  Andradite crystals cemented together by iron oxides.

AD-210  Calcite, Quartz and Barite geode  SOLD

Juchem Quarry, Niederwörresbach, Herrstein, Birkenfeld, Rhineland-Palatinate, Germany

13.6 x 9 x 8.5 cm

Here we have a whopper of a geode. This geode is lined with tiny crystals of Quartz upon which rest many golden-colored crystals of Calcite. The crystals in the rear of the chamber are coated by the mineral Barite. The Calcite fluoresces a creamy-yellow and the Barite fluoresces white.

C-281  Chabazite-Ca on Calcite  $85

Juchem Quarry, Niederwörresbach, Herrstein, Birkenfeld, Rhineland-Palatinate, Germany

14.4 x 12.2 x 7.4 cm

Here we have an example of one of the more elusive mineral species from the Juchem Quarry, Chabazite-Ca. This specimen features many twinned and translucent\transparent crystals of Chabazite perched on opaque prisms and massive Calcite which exhibit an intense red-colored fluorescence. While I have heard of Chabazite from this location, I had not, until a few years ago, actually seen one other than one photo on Mindat. The fact that this locality has been heavily collected and that Mindat has only one photo of this mineral from this locality attests to its rarity.


Agate, Cubuk, Ankara Province, Central Anatolia Region, Turkey

AD-211  Agate  $35

Cubuk, Ankara Province, Central Anatolia Region, Turkey

8.7 x 5 x 2.6 cm

An Agate comprised of various shades of blue and of red. Around a portion of the rim are pseudomorphs after Anhydrite. When the Agate nodules are more completely filled with these pseudomorphs the are known by the locals as “Stick Agate”. There are many colorful Agates that recently being found at this location and it is slowly getting the recognition that it deserves.

S-163  Stilbite  $50
Ex R. Rizzo Collection

Mawi Pegmatite, Nilaw-Kolum Pegmatite Field, Du Ab District, Nuristan, Afghanistan

3.9 x 2.7 x 2.7 cm

While not unheard of, Zeolite minerals in pegmatites are not that common. Especially when it comes to Afghanistan where the only other pegmatite occurrence of a zeolite mineral are the Pollucite crystals from 15-20 years ago. This specimen features many well-formed and undamaged crystals of honey-brown-colored Stilbite. I'd seen several of these associated with Kunzite a few years back but that was it for this find. This specimen would make a fine addition to anyone's collection of pegmatite or zeolite minerals.

S-164  Stilbite  $35

Mount Etna, Pine Grove Hills, Wilson Mining District, Lyon County, NV

3.7 x 2.4 x 2.4 cm

A vibrantly-colored bundle of Stilbite crystals from the middle-of-nowhere, Nevada. I've lived in northern Nevada for 17 years and this is the first and only example of this material that I have encountered. A great addition to anyone's suite of zeolite minerals.

Mezica Mines, Mezica, Carinthia Region, Slovenia

9.4 x 7.5 x 4.4 cm

A large specimen of Wulfenite from a classic locality. The crystals of this specimen have a nice butterscotch color and some lustre. Judging by the label, this Wulfenite specimens a real old-timer. While not pristine, this specimen is is in good condition for its age.
