Gallery 1 Mixed Mineral Specimens
with Birnessite, Calcite, Natrolite, Rhodochrosite & Willemite $675
Poudrette Quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada
14 x 7.5 x 5.9 cm
This large, divergent spray of blade-like Serandite crystals has partially altered to the Mn Oxide mineral, Birnessite. These Birnessite-Serandite combos are considered to be among the more noteworthy specimens to occur at Mont Saint-Hilaire. This specimen was collected in 1975, when the best examples of these were found. This spectacular specimen also features a well-formed cluster of dark yellow Calcite crystals and another smaller cluster of light yellow Calcites. The pair of Calcite clusters exhibit strong fluorescence under both short and long wave ultraviolet light. Near the right-hand side of this specimen is a 2 x 1.5 cm tabular Rhodochrosite crystal that has partially altered to Birnessite. As is typical with many Serandites, this specimen is liberally encrusted with Natrolite crystals ranging from white to colorless. Among the Natrolite crystals are several Willemite crystals that exhibit both strong neon-green fluorescence and phosphorescence.
This amazing specimen was one of the few specimens that were chosen from Mr. Wadell's vast collection of minerals for inclusion in the photo essay authored by Steven C. Chamberlain that appeared in volume 9, number 2 of The Mineralogical Record.
AD-237 Heulandite & Mordenite $275
Rat's Nest Claim, Challis, Bay Horse Mining District, Custer County, ID
17.8 x 15.2 x 10.3
A very large vug (or geode if you prefer) of salmon-pink-colored crystals of Heulandite on a bed of snow-white Mordenite. The well-formed, pinkish Heulandite crystals on the underlying white-hued Mordenite makes for a pleasing contrast of colors. This is one of the largest and one of only a small handful of complete vugs that were recovered during mining in the early 2000's. This specimen was obtained directly from miner in 2006. This deposit has long been depleted of collector quality specimens for some time now.
G-141 Goethite $85
Filón Sur Open Pit, Tharsis Mines, Tharsis, Alosno, Huelva, Andalusia, Spain
7.8 x 5.1 x 3.6 cm
Goethite in a stalactitic-botryoidal growth with intense, very bright, iridescent metallic reflections. The colors vary between blue, blue-green and red and are more pastel than usual for this find. The specimen is from a find in 2007. Other than a handful of these specimens, this locality hasn't produced significant samples in the last 30+ years. Although contacted on top and bottom it is a very fine example of this material.
B-220 Barite $65
Baia Sprie Mine, Baia Sprie, Maramures County, Romania
8.1 x 5 x 4.5 cm
Here we have a cluster of thin pale, blue-grey Barite crystals on matrix. This three-dimensional specimen features fans of Barite crystals measuring up to 2.1 cm in size. These blue Barite specimens are some of the most desirable of the species from this location.
F-222 Adularia $45
Hamilton Hill Mine, Jessieville, Garland County, AR
8.3 x 7.6 x 4.3 cm
A mound of bone-white Adularia crystals. The specimen has a slightly pearlescent lustre. This specimen is from a small project in 2013 that yielded Adularia and Quartz combination specimens. Hamilton Hill has been worked intermittently for over 150 years. Quartz crystal mining was begun at Hamilton Hill shortly after the Civil War by William Hamilton and John Neal. Hamilton Hill reputedly produced the largest volume of crystals of any of the old mines in the Garland County area. It was particularly well known for producing important collector specimens.
B-209 Barite $45
Congreso-León Mine, San Pedro Corralitos, Municipio de Casas Grandes, Chihuahua, Mexico
4.6 x 3.1 x 2.1 cm
This aesthetic specimen of Barite consists of very thin group of pointed tabular blades to 3.3 centimeters perched on gossan matrix. There is also a secondary growth of smaller Barite crystals on one side of the specimen. These specimens were collected by mineral dealer Benny Fenn around 1970-71.
U-003 Ulexite $40
U.S. Borax Mine, Kramer Borate Deposit, Boron, Kern County, CA
4.7 x 4.1 x 3 cm
A knobby mass of intergrown, fibrous micro-crystals of Ulexite. Tons of this material have been mined at Boron, and placed on the borate dumps for long term storage. Most collectors are familiar with the parallel acicular Ulexite crystals from this location but few collectors ever bothered to collect this compact, nodular material or had the patience to clean the mud out of all the nooks and crannies of the specimens. This is old material that was only found near the top of the borate deposit at Boron.
O-023 Opal $220
Rainbow Ridge Mine, Virgin Valley, Humboldt County, NV
6.1 x 5.1 x 4.6 cm
This colorful specimen is section of a limb from a conifer tree that has been replaced by Opal. This specimen has been dried out and has a good play of colors, mostly greens and reds. Virgin Valley is considered to be the premiere source of precious opal in the United States. The Roebling Opal, one of the more famous Opals from Virgin Valley was mined at Rainbow Ridge about 1918 and is in the collection of the Smithsonian Institution in Washington, DC.
P-074 Pyrite bar $225
Buick Mine, Bixby, Iron County, MO
10.4 x 4.9 x 4.8 cm
A stout, Pyrite bar from the famous Buick Mine in the Viburnum Trend of Missouri. This specimen exhibits a medium lustre and has slight twist which is common for these “bars”. These specimens were recovered about 40 or so years ago and are considered to be classics.
C-238 Chalcopyrite $50
Huaron Mines, Huaron Mining District, Pasco Province, Pasco Department, Peru
4.5 x 3.9 x 2.9 cm.
Here we have a very large, for its species, twinned crystal of Chalcopyrite perched on a matrix of Sphalerite. As an accent to this specimen there are several Quartz crystals. A very attractive miniature-sized specimen. Not your usual, run of the mill Peruvian sulphide specimen.
K-008 Kyanite on Quartz $40
Barra do Salinas, Coronel Murta, Minas Gerais, Brazil
6.2 x 5.5 x 3.3 cm
A 6 centimeter crystal of dark blue-colored Kyanite set in a matrix of quartz. Kyanite is generally seen in the form of opaque whitish-blue crystals embedded in chunks of Quartz. But occasionally, you get a darker blue crystal such as this, perched dramatically on the matrix. Kyanite is an unusual mineral in that it has a Moh's hardness of 4.5 parallel to the length of the crystal and a hardness of 6.5-7 across the width. Kyanite was once commonly called "disthene" which means "two strengths."
C-294 Corundum variety Sapphire $35
Beitbridge District, Matabeleland South, Zimbabwe
4.6 x 3.7 x 3 cm
A blue-gray crystal of Sapphire with a little bit of Biotite. This crystal has some lustre and is complete except for a small area of contact. 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:
S-134 Stellerite $50
Aurangabad District, Maharashtra, India
5 x 4 x 2 cm.
Fine crystallized Stellerites are only found in a handful of localities worldwide. Stellerite is a species very close in structure and chemistry to Stilbite and can be mistaken for Stilbite. Both Stellerite and Stilbite occasionally assume a bow-tie-like form. This specimen is an example of this type of formation taken to the extreme and in my opinion that sets it above the majority of examples of these types of specimens. The light-peach-colored Stellerite presented here has a good lustre and presents well in any number of different orientations.
AD-217 Calcite, Datolite, Prehnite geode $80
Tiso, Funes, South Tirol, Trentino-Alto Adige, Italy
11.3 x 8.8 x 7.4 cm
Here we have an example of what the locals call “Teis spheres”. “Teis spheres” are well-known in Europe ; they are basaltic geodes filled with well-crystallized minerals. This large, egg-shaped geode is filled with Prehnite balls, Calcite rhombs and crystals of Datolite.
S-131 Strontianite on Fluorite with Chalcopyrite $175
Minerva #1 Mine, Ozark-Mahoning Group, Cave-in-Rock, Hardin County, IL
9.7 x 6 x 5.7 cm
Acicular white to colorless Strontianite crystals on a matrix of crystallized Fluorite. The spiky, minute crystals in radiating tufts, as seen on this specimen from the Minerva #1 Mine are a great example of the species from this closed locality. This specimen has a lot of presence. Strontianite is a rare carbonate mineral (strontium carbonate) and one of only a handful of known strontium minerals. Crystals are rarer than the massive forms.
H-093 Halite $80
Wieliczka Mine, Wieliczka County, Lesser Poland Voivodeship, Poland
10.2 x 9.4 x 5 cm
A group of translucent to transparent crystals of Halite from Poland's most famous mineral location. The color of the crystals are a light off-white and the specimen has a satiny or matte finish. This specimen also has a good red-colored fluorescence.
C-307 Charoite (Type Locality) with Steacyite & Aegerine $250
Murunskii Massif, Chara & Tokko Rivers, Aldan Shield, Russia
19 x 12.6 x 6.1 cm
A very large example of lilac-purple-colored Charoite from the type locality for this species. Charoite, is a rare & very complex silicate mineral & is well-known as exceptional lapidary material due to its beautiful violet to deep lilac color. The Charoite serves as a host for numerous radial sprays of lustrous, green-black Aegerine & yellow-brown-colored crystals of the rare Th-silicate mineral, Steacyite. The Steacyite also has a killer green-colored fluorescence. Charoite is named for the type locality, near the Chara & Tokko Rivers.
H-087 Halite $60
Searles Lake, San Bernardino County, CA
9.1 x 7.8 x 5.4 cm
A very sculptural and three-dimensional specimen of Halite. The color of this specimen is natural, not dyed. These specimens owe their color to algae that is trapped inside the Halite crystals when they grow near the surface of the lake.
A-122 Axinite-(Fe) $185
Puiva Mount, Saranpaul, Khanty-Mansi Autonomous Okrug, Russia
8 x 5.6 x 3 cm
A plate of mostly transparent crystals of razor-sharp, bladed crystals of Axinite-(Fe). The crystals on this specimen have a good lustre and pleasing clove-brown color with just a hint of purple. All of the crystals on this specimen are complete, several of which sport a coating of green-colored Chlorite. In the early 1990's excellent specimens of Axinite-(Fe) were available from this extraordinary alpine-cleft deposit in the Polar Urals. Little from here, at least in good quality, appears to be available today. Axinite specimens from Puiva are considered to be world-class in quality. Named Axinit in 1797 by Rene Just Haüy (Haüyne) from the Greek "axina" or "axe", in allusion to the common habit of its crystals. Renamed Ferroaxinite by Waldemar T. Schaller in 1909 for iron dominance in the formula. Renamed with suffix "-(Fe)" by the IMA in 2007.
S-141 Siderite, Dolomite, Albite, Pyrrhotite and Quartz $185
Morro Velho Mine, Nova Lima, Iron Quadrangle, Minas Gerais, Brazil
9 x 7.6 x 6.4 cm.
This specimen hails from the world's oldest continually producing gold mine, started in 1725. Present on this specimen are lenticular crystals of Dolomite to 2.4 cm. and very clear Siderite crystals to 2.0 cm. in size. Most notable though, are the numerous crenellated Albite crystals measuring up to 3.3 cm. in size. Albite is not often seen on specimens from this famous location, especially in crystals this large. Both Siderite and Dolomite from Morro Velho are considered world-class in quality. Also found on on this specimen are clear and gemmy Quartz crystals and the ever present Pyrrhotite.
C-255 Corundum variety Sapphire $160
Bawmar, Kyatpyin North, Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Burma
5.3 x 4 x 2.7 cm
Here we have an alluvial Sapphire crystal from one of Asia's more prolific gem producers. This crystal still has some of its matrix attached. This Sapphire has a medium-yellow color that is stained red by iron that has leached from the piece of the crystal's host rock that is still attached. Despite being river-tumbled, this Sapphire shows good form. This specimen would make a colorful addition to any collector's mineral cabinet.
on Gypsum $65
Eureka County, NV
5.7 x 4.6 x 3.0 cm.
Here we have an old-timer Nevada Sulphur specimen with well-defined, translucent-to-transparent crystals to just under 1 cm. on a matrix of white Gypsum. While the specimens from Steamboat Springs, just south of Reno get all the accolades when it comes to Nevada Sulphur crystals, these specimens from Eureka County are every bit as good. Examples of this material are nearly impossible to come by, even for those of us that live in northern Nevada.
W-028 Wulfenite & Mottramite $50
Ojuela Mine, Mapimí, Municipio Mapimí, Durango, Mexico
7.9 x 4.5 x 5 cm
This specimen features many pyramidal crystals of butterscotch-yellow-colored Wulfenite in and on a nest of dark-green-colored Mottramite.
A-124 Apophyllite $85
Mahodari, Sinnar, Nashik District, Maharashtra, India
5.8 x 5.7 x 5 cm
A stout and fully formed crystal of umber-yellow & brick-red Apophyllite. This floater crystal has a good form and a good lustre. These unusual specimens of included Apophyllite from several small finds in 2003-2004 became instant classics when they first appeared. Marketed as “Marshy Apophyllite” the inclusions were said to be Mozartite, a rare Ca-Mn silicate, but that has since been discredited. The inclusions were later determined to be clays or Chlorite. The red inclusions are iron oxides.
G-113 Grossular Garnet $195
Jeffrey Mine, Asbestos, Les Sources RCM, Estrie, Québec, Canada
7.7 x 5.6 x 1.6 cm.
A very gemmy specimen of Grossular from the renowned Jeffrey Mine in Asbestos, Canada. This specimen is covered with well-formed Grossular crystals, the largest ones measuring 1 centimeter. The color of the crystals range from pink to peach to cinnamon-brown. All of the Garnet crystals are water-clear with a great, gem-like lustre, with the exception of several small crystals on the crystals on edge of this specimen.
AD-204 Prehnite & Natrolite nodule $50
Wave Hill, Victoria-Daly Region, Northern Territory, Australia
7 x 4.3 x 3.2 cm
This specimen hails from a locality that is better known for the Amethyst specimens and the Agate specimens that are found there. This nodule features a center of white, Natrolite surrounded by very clear, green-colored Prehnite.
P-076 Plumbogummite & Pyromorphite $225
Yangshuo Mine, Guilin Prefecture, Guangxi Zhuang Region, China
4.7 x 4.6 x 2.8 cm.
This specimen consists of a slightly divergent cluster of Pyromorphite crystals to 4.5 cm. in length that have been mostly replaced by the sky blue lead phosphate mineral Plumbogummite. Most of the crystals exhibit hopper growth at their terminations. Basal portions of the crystals still have remnants of the original Pyromorphite. A great example from the pocket with medium-sized pyromorphite crystals for this find, which would be huge by any other standard.
G-145 Andradite Garnet $40
Tepustete Ranch, Álamos, Municipio de Álamos, Sonora, Mexico
8.2 x 5.2 x 3.1 cm
Numerous green to dark green Andradite crystals scattered on a matrix of Quartz. The crystals on this specimen are mostly translucent. Examples of this material are seldom seen for sale.
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.
Q-488 Quartz with Pyrite & Pyrrhotite on Galena $60
Trepca Stan Terg Mine, Trepca Valley, Kosovska Mitrovica, Kosovo
8 x 5.1 x 5.3 cm
This specimen consists of multiple crystals of clear, glassy Quartz crystals on a matrix of Galena. Also present on this specimen are crystals of Pyrrhotite that have been coated by tiny, sparkly crystals of Pyrite.
A-114 Aragonite $70
Bristol Mine, Bristol and Jackrabbit Districts, Lincoln County, NV
12.3 x 11.9 x 7.9 cm
This very three-dimensional formation of Aragonite is from a defunct silver mine. These specimens are formed by ground water deposition inside the underground mine.
S-147 Stilbite $35
Paterson, Passaic County, NJ
6.8 x 4.9 x 3.3 cm.
A specimen of well-terminated, yellow-orange crystals of Stilbite measuring up to 8 mm on a basalt matrix.
G-159 Spessartine on Muscovite $65
Nani Hill, Loliondo, Ngorongoro District, Arusha Region, Tanzania
6.3 x 3.8 x 1.9 cm
This specimen consists of two orange-colored Spessartine crystals, the largest measuring 1.1 cm across, in a mica rich matrix. Complete all around and damage-free. Range-colored Spessartine garnets are not that common and are only found in a handfull of localities.

Mezica Mines, Mezica, Carinthia Region, Slovenia
14.6 x 12.5 x 6.7 cm
A large matrix specimen from one of Europe's more noteworthy Wulfenite locations. This specimen features greenish-brown crystals of Wulfenite sandwiched between secondary overgrowths of orange-yellow Wulfenite. Also present are smaller dipyramidal crystals as singles and small groups. The Crystals on this specimen measure up to 1.6 centimeters in size.
F-267 Adularia variety Valencianite (type locality) $65
Valenciana Mine, Municipio Guanajuato, Guanajuato, Mexico
11 x 7.6 x 3 cm
A good sized plate 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 3 centimeters, many of which exhibit a slight curvature. An excellent example of a lesser known variety of Feldspar. Valencianite is rarely seen for sale these days, let alone specimens from the type locality. A great addition to anyone's suite of Mexican mineral specimens or one's Feldspar collection. All right all of you closet Feldspar collectors (like myself), here's your chance to get a great deal on a rare variety of Feldspar from the type locality.
F-268 Adularia variety Valencianite (type locality) $55
Valenciana Mine, Municipio Guanajuato, Guanajuato, Mexico
13.6 x 8.5 x 1.7 cm
A good sized plate 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 3.2 centimeters, many of which exhibit a slight curvature. A good example of a lesser known variety of Feldspar.
K-009 Kyanite $35
Sultan Hamud, Umba Valley Region, Makueni County, Kenya
6.3 x 1.7 x 1.2 cm
An example of old-time, hard to find material from southern Kenya. This crystal is terminated and has no damage. Kyanite is an unusual mineral in that it has a Moh's hardness of 4.5 parallel to the length of the crystal and a hardness of 6.5-7 across the width. Kyanite was once commonly called "disthene" which means "two strengths."
P-087 Prehnite $40
Luck Stone Quarry, Bealeton, Fauquier County, VA
6.7 x 5.5 x 5.6 cm
This lustrous specimen of mint-green-colored Prehnite features crystals up to 1 cm in size. Mineral specimens of any species are extremely rare from this obscure Virginia quarry. In fact, mindat.org only has 2 examples of Prehnite from this location.
W-024 Witherite & Barite $165
Nentsberry Haggs Mine, Alston Moor, Cumbria, United Kingdom
10.6 x 9 x 6.1cm.
The region of England known as Cumbria has a rich mining history that goes all the way back to the time of the Roman occupation and, for some time, been regarded as a mineral collector's paradise, being a prolific producer of more than 300 different species. This chunky specimen of Witherite is larger than most from this mine. The crystal is complete and exhibits a white coating which is an alteration to the mineral Barite. This specimen was recovered in the area of the mine known as Admirality Flats, more specifically the High Raise Second Sun Vein.
G-123 Hessonite Garnet with Clinochlore $65
Ala Valley, Lanzo Valleys, Torino Province, Piedmont, Italy
10.3 x 7.2 x 3.1 cm.
This colorful specimen hails from the alpine veins of Val d’Ala, Italy. This matrix specimen is covered in glassy and gemmy, wine-colored Garnets, to .9 centimeters across. They are lustrous and sparkling, especially the smaller ones, and quite beautiful. Associated with the Garnets is the ever present (at least when it comes to alpine-type mineral deposits) Clinochlore which makes for a nice contrast of colors.
P-079 Pyrite $50
Rensselaer Quarry, Pleasant Ridge, Jasper County, Indiana
4.3 x 4.5 x 2.6 cm.
A great old Indiana Pyrite, with sharp, well-formed, modified pyritohedrons perched very attractively on a micro crystal-covered matrix. Though there are plenty of Peruvian and Spanish pyrites around, you don't see many of these Indiana ones around. The Rensselaer Quarry had a reputation as an extremely challenging quarry to extract specimens from. Many of the specimens from here were coated in thick hydrocarbons. This location has been flooded and closed for some time now.
G-087 Galena and Chalcopyrite $60
Joplin Field, Tri-State District, Jasper County, Missouri
5.5 x 5 x 4.5 cm.
This is an old Tri-State Galena specimen that is truly amazing to look at, in that its surface is completely covered with small, flat-topped epitaxial Galena crystals resulting from a second generation of growth. The main crystal is complete, with the back side being L-shaped where it was wrapped around the matrix rock. The Galena also has many tiny, golden Chalcopyrite crystals, which add to the specimens attractiveness.
Calcite and Pectolite $135
Poudrette Quarry, Mont Saint-Hilaire, Québec, Canada
8.5 x 7.5 x 5.4 cm.
A matrix specimen consisting of two 3-centimeter rhombohedral Siderite crystals surrounded by several smaller crystals, accented with clusters of grayish Calcite crystals and sprays of white Pectolite crystals. One of the larger siderite crystals has trivial wear on its corner, which in my opinion does not detract from the overall appearance of this specimen. The Calcite on this mineral specimen fluoresces red under shortwave ultraviolet illumination.
