C-288  Calcite on Fluorite  $100

Minerva #1 Mine, Ozark-Mahoning Group, Cave-in-Rock, Hardin County, IL

8.6 x 5 x 4.6 cm

I've seen a lot of Calcite from Cave-in-Rock over the years but this is the first time I've ever encountered a specimen such as this. This specimen consists of flattened rhombs of translucent, honey-colored Calcite with lighter colored edges on an elongated crystal of Fluorite. The Calcite crystals fluoresce a mild orange color.

C-291  Cavansite (TL) & Heulandite  $50

Owyhee Dam, Lake Owyhee State Park, Malheur County, OR

3.2 x 2.5 x 2.9 cm

This specimen features bright-blue-colored, radial sprays of Cavansite with sparkly Heulandite crystals richly covering the basalt matrix of this specimen from the Type Locality. First described in 1967, the Owyhee Dam specimens were what you got if you wanted a Cavansite for your collection. The Indian discoveries of the late 1980's changed that. This piece has historical and scientific importance. None of these have been found in many years, to my knowledge.

T-330  Turquoise & Perhamite  $40

Silver Coin Mine, Valmy, Iron Point Mining District, Humboldt County, NV

4.7 x 3.5 x 3.7 cm

This specimen features a pair of phosphate minerals. Sprays of green-blue-colored Turquoise accompanied by balls of Perhamite. Perhamite is an uncommon phosphate mineral, while crystallized Turquoise is not that common either. The Silver Coin Mine is regarded as a world-class location for crystallized Turquoise.

F-264  Amazonite  SOLD

Wimmer No. 3 Pit, Nine Mile Pluton, Wausau Intrusive Complex, Marathon County, WI

4.2 x 3.6 x 3.5 cm

An example of Amazonite from the northeastern Wisconsin granite pluton (Wausau Complex). The granite is cut by numerous complex pegmatites, yielding an array of interesting minerals. When it comes to Amazonite, Colorado is king. However, Amazonite is found at many other localities, both in the USA and worldwide. Most of the other localities are often overlooked or just don't have the reputation that Colorado has. The body of this specimen is white to pale-blue and the termination is a darker shade of blue.

C-289  Copper  $85

Keweenaw County, MI

10.4 x 9.1 x 2 cm

Here we have an example of amygdular Copper. Michigan is well-known for outstanding crystallized Copper specimens. Rounded solid Copper amygdules are rare. This example is a sawn half which could be polished if desired. Amygdules form when the gas bubbles or vesicles in volcanic lava (or other extrusive igneous rocks) are in-filled with a secondary mineral such as Calcite, Quartz, Chlorite or one of the zeolite minerals. In this case the mineral is Copper.

AD-213  Goethite geode  $100

Dumbalk, South Gippsland Shire, Victoria, Australia

16.5 x 12.4 x 6.4 cm

A large, Goethite geode with highly lustrous interior. Some areas of of the interior exhibit a faint iridescence. I see these for sale every now and then, usually 6-7 cm in size, but this is the first one of this size that I have encountered.

E-034  Epidote  $85

Green Monster Mountain, Prince of Wales Island, Ketchikan District
Prince of Wales-Hyder Census Area, Alaska

7.1 x 2.7 x 3.6 cm

This Epidote specimen comes from a mineral location that Peter Bancroft dubbed as one of the world's most inaccessible areas and a wild and forbidding spot to collect. Fine Epidote specimens from this remote location have been known for over 100 years and are much prized by collectors and in my opinion they are among the finest examples of this mineral species. This specimen is comprised of deep-green and highly lustrous, prismatic crystals of Epidote in a fan-shaped aggregate. It is in superb condition and all of the crystals are undamaged with the base being contacted where it formed against the pocket wall.

Z-005  Zeunerite  $45

Majuba Hill Mine, Antelope Mining District, Pershing County, NV

2.4 x 2.2 x 1.7 cm

Here we have a matrix specimen of the uncommon hydrated copper uranyl arsenate mineral, Zeunerite. The Zeunerite crystal measured a little over 7 mm and is considered to to be much larger than average in size for this location.

F-269  Albite pseudomorph after Scapolite  $50
Ex R. Waddell, T. Fitzpatrick, R. Rizzo

Poudrette Quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

5.3 x 3.6 x 2 cm

Here we have an example of Pink colored Albite that has replaced a group of Scapolite crystals. The pink Albite from Mont Saint-Hilaire are usually found as aggregates of bladed crystals and are much sought after by collectors. This uncommon example of pink Albite is somewhat of a rarity; I have only seen 2 other examples of this material. These specimens were recovered from 2 pockets near the entrance to the quarry on August 27, 1989 by Gilles Haineault. Specimens from this classic location are getting hard to come by as collecting is restricted to one or two field trips per year, to small groups (drawn by lottery) of members of the Club de Minéralogie de Montréal, under very strict rules.

Q-500  Smoky Quartz  $75

Poudrette Quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

6.2 x 2.2 x 2.1 cm

When one thinks of pegmatites, one usually assumes that a significant portion of the minerals found there will be Quartz. However, at Mont Saint-Hilaire, this is not the case as most of the Quartz crystals are found in the non-pegmatite rock formations. While Quartz crystals to 15 cm. have occasionally been found, they are typically opaque & crudely formed. This translucent, double-terminated Quartz crystal exhibits multiple stages of growth with distinct color zoning throughout the crystal. Specimens from this classic location are getting hard to come by as collecting is restricted to one or two field trips per year, to small groups (drawn by lottery) of members of the Club de Minéralogie de Montréal, under very strict rules.

G-157  Andradite pseudomorph after Quartz  $40

Stanley Butte, Santa Teresa Mountains, Graham County, Arizona

3.2 x .7 x .5 cm

Here we have an example of one of the more unusual pseudomorphs that I have encountered over the years. This specimen consists of a Quartz crystal that has been replaced by light-green-colored Andradite Garnet.


Albite, Magnet Cove, Hot Spring County, Arkansas
click on image for larger view

F-266  Albite  $45

Magnet Cove, Hot Spring County, Arkansas

8.5 x 9.4 x 6.6 cm

When it comes to Magnet Cove, people will primarily think of its famous titanium minerals like Rutile, Brookite and Perovksite, along with rarities like the Garnet species Kimzeyite. Few people think of a species like Albite when it comes to Magnet Cove. This specimen features many well-formed crystals of Albite that have formed knobs or rosettes that give the specimen 3-dimensionality. These specimens were a one-off find made 20+ years ago.

F-263  Adularia variety Valencianite  $75

Silver City Mining District, Owyhee County, Idaho

8.7 x 8.2 x 3 cm

A good sized example of lustrous crystals of the variety of Feldspar known as Valencianite, whose name comes from the mine that it was first identified from. This specimen features crystals measuring up to to 2.6 cm. While Valencianite from the type locality can be found if you look really, really hard; Valencianite from the other three localities from which it is known are only encountered once in a blue moon if you are lucky.

Malbunka Copper Mine, Areyonga, Gardiner Range
MacDonnell Region, Northern Territory, Australia

7.6 x 6.1 x 2.9 cm

The Azurite “suns” from the Malbunka Copper Mine form in a fashion that is unlike any other Azurites that I've seen. These flattened discs of Azurite are formed between layers of Kaolinite which forced them to grow in a laterally compressed, radiating manner. The Azurites on this specimen have beautiful deep-blue color and an interesting texture.

G-158  Andradite Garnet  SOLD

Kohse Mine, Tenkawa Village, Yoshino District, Nara, Japan

1.4 x 1.4 x 1.5 cm

Mined out of a small metamorphic skarn, these iridescent "rainbow garnet" Andradites came on the market in 2002 and have not been equaled since. They are unique in the world and their look is unmistakable; with an electric luster and mahogany color with flashes of blue, green, yellow and red. Although several potions of the crystal are contacted it does detract from the overall appearance of the specimen. Measuring 1.4 cm in size; this crystal is a little larger than average for this find. Collecting is now prohibited at this Magnetite mine and these are seldom seen and rarely available.

T-333  Elbaite Tourmaline with Lepidolite  $40

Aletai Prefecture, Yili Hasake Autonomous Prefecture, Xinjiang, China

1.7 x .6 x .6 cm

Here we have a Tourmaline from a an area of China that is better known for the Aquamarine that is found there, Most of which goes straight to the gem cutters to make jewelry. This specimen is from a find made in 2006. This very clear Tourmaline has a light-pink color that grades to a medium-green with a small area of the termination being greenish-black. I've seen very few examples of this material over the years. More than 10,000 pegmatite veins are known in the Altay range. Many of them are worked for gemstones and rare metals.

T-334  Elbaite Tourmaline & Lepidolite  $95

Urubu Mine, Monte Belo, Itinga, Minas Gerais, Brazil

4.5 x 2.9 x 1.7 cm

Tourmaline is not a mineral that most people associate with pseudomorphing/replacement, but the Tourmalines from the Urubu Mine are some of the most distinctive and interesting examples out there. This piece is actually a really interesting replacement specimen as it started out as a solid crystal of green Tourmaline which has been replaced by white translucent Quartz. The interesting aspect is that the replacement took place from the center of the crystal. The Tourmaline crystal is partially enveloped by a group of Lepidolite crystals. This crystal is not your run of the mill Urubu Mine Tourmaline specimen that there seem to be so many of, most of them opaque and unterminated.

Padre Paraíso, Minas Gerais, Brazil

8.7 x 2 x 1.7 cm

A gemmy and stout, single crystal of bi-colored Beryl with great color and better clarity than can be seen in these photographs. This crystal has a rich yellow color and a faint, Aquamarine-colored termination. This double-terminated crystal shows unusual etching patterns around its surface which makes for a texture that feels just a little bit rough to the touch, although it certainly appears smoother from a distance. The visual effect is to make the surface more sparkly from the extra minute reflection points. An excellent Brazilian Beryl from a modern-day classic location.

San Cristobal Pegmatite, Municipio Suaita, Santander Department, Colombia

7.7 x 1.7 x 1.8 cm

An excellent example of Citrine. This specimen is complete all around and has a rich color, unlike most of the specimens that were found, which were usually pale lemon-yellow to almost no yellow at all. Natural Citrine Quartz crystals are uncommon worldwide. These Citrine specimens were available for a short time in the late 1980's - early 1990's but are rarely encountered these days.
