Gallery 1 Mixed Mineral Specimens
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.
A-124 Apophyllite $80
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-162 Andradite Garnet $350
Tepustete Ranch, Álamos, Municipio de Álamos, Sonora, Mexico
6.6 x 5.2 x 7.2 cm
A large, dark green Andradite Garnet crystal 6.6 cm tall. The surface has a decent lustre with olive-colored spots. These are truly unique specimens. I have only seen one other example of this material. The book Minerals of Mexico says Andradite crystals occur here up to 5 cm - this one is an impressive 6.6 cm. This specimen comes with a custom made acrylic base.
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.
F-285 Adularia $50
Alchuri, Shigar District, Gilgit-Baltistan, Pakistan
5.6 x 5.2 x 3.8 cm
An unusually-colored and double terminated crystal of Adularia. This specimen has a satin-like lustre. also present on this specimen are small crystals of Albite and Actinolite. These brown-colored Adularia crystals are from a one-off find in 2012-13. Alpine localities are well-known for producing superb Adularia specimens, but there are a few "Alpine-type" localities in the Himalayas of Pakistan that produce some great specimens in their own right. Adularia is a variety of Orthoclase and is most commonly associated with metamorphic deposits such as those in the Alps. The person that I purchased these crystals from said that the color was due to Astrophyllite inclusions which I think is unlikely, most likely is that the color is due to inclusions of one of the Amphibole group minerals.
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.
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.
AD-222 Barite nodule $60
Portaway Mine, Peak Forest, High Peak, Derbyshire, England, UK
7.3 x 5.6 x 4 cm
This weighty nodule features bands of burnt-orange and yellow surrounding tightly-packed crystals of Barite with a hollow center.
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.
on Quartz $85
Le Trient Valley, Valais, Switzerland
9.6 x 7.2 x 4.1 cm
This specimen features striated, lustrous, brown-hued blades of Brookite to 8 mm in size. The Brookite crystals are richly scattered and hidden on the jackstraw matrix of variably-sized, glassy Quartz crystals. This specimen hails from the famous Trient Glacier of Switzerland. The largest Quartz crystal on this specimen measures 4.4 cm in length. This specimen came from noted Alpine collector Rolf Wein and was purchased at the Basel Show in 1972.
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.
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.
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.
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.
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.
Apophyllite, Calcite & Natrolite SOLD
Bergen Hill, Hudson County, NJ
13 x 11.6 x 4.9 cm
This specimen is comprised of translucent, light golden color Calcite scalenohedra which are associated with white blocky Apophyllite crystals and small acicular "sprays" of Natrolite on matrix. The locality at Bergen Hill dates back to the 19th Century, and some of the most classic of all New Jersey Trap Rock specimens have been found around this area.
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.
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.
C-254 Corundum variety Sapphire $165
Wellawaya, Moneragala District, Uva Province, Sri Lanka
8.6 x 6 x 2.3 cm
This specimen is something you is almost never seen from Sri Lanka, a Sapphire crystal in matrix. Matrix specimens are all but unheard of. The main Sapphire crystal on this specimen is double-terminated and has a reddish-purple hue. The other crystals in the matrix of this specimen are lighter in color with some being translucent. Sri Lanka has long been known for its seemingly endless supply of Sapphires. Gemstone mining in Sri Lanka is from secondary deposits. The gravels yield Sapphire, Ruby and many other gemstones. Sri Lanka’s gem-bearing gravels, called illam, are some of the richest in the world. The island was blessed with geological conditions that provide an ideal blend of chemistry, heat, pressure, time for gem crystals to grow, and weathering for the gem crystals to be deposited and concentrated in gravels.
B-210 Barite on Fluorite $150
Xiefang Mine, Ruijin County, Ganzhou Prefecture, Jiangxi Province, China
8.5 x 6.8 x 5 cm
This specimen features blocky to tabular, honey-brown Barite crystals to 1.6 are studded on a matrix of green-colored Fluorite crystals. The Fluorite is contacted on the back, which I think is better than being sawn like many of these were. This specimen is from a find in China about 10-12 years ago. Sadly, very few of these colorful specimens came out, and it looks like no more will.
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.
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.
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.
C-293 Corundum variety Ruby $70
Jegdalek Ruby Deposit, Surobi District, Kabol Province, Afghanistan
6 x 5 x 4.1 cm
An specimen of Ruby on matrix. The Ruby crystal on this specimen measures 1.3 cm and is translucent. The color of this Ruby is very pleasing to the eye and fluoresces violently when exposed to SW or LWUV.
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.
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.
B-235 Barite on Calcite RESERVED
Meikle Mine, Bootstrap Mining District, Elko County, NV
9 x 8 x 6 cm
This specimen features lustrous, honey-colored Barite crystals on a mound of grayish to colorless flattened rhombohedral Calcite crystals. The crenellated Barite crystals on this specimen are mostly clear and are damage-free. The meikle Mine is part of the Goldstrike mine complex which is the largest Carlin-type mine in the world.
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.
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 just as good. Examples of this material are nearly impossible to come by, even for those of us that live in northern Nevada.
W-026 Wulfenite $85
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.
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.
W-025 Wulfenite $145
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.
S-091 Stilbite $75
Jalgaon, Maharashtra, India
11.5 x 6.4 x 4.6 cm.
This specimen features a pair of bow-tie shaped Stilbite crystals included by the mineral Celadonite. I've seen lots of Celadonite included Heulandite crystals, but not very many of these Celadonite-included Stilbites. From what I have seen I have a feeling that there are not too many of these out there as I had to go through quite a few specimens to find this one.
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.
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.
Q-488 Quartz with Pyrite & Pyrrhotite on Galena $60
Trepca Stan Terg Mine, Trepca Complex, 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.
P-072 Pyrite $65
Rio Marina, Elba Island, Livorno Province, Italy
7.2 x 6.7 x 3.9 cm.
The mineral wealth of Elba has been exploited since Etruscan times. It is a small wonder that there is anything left these days. No significant finds of Pyrite have been made here since the 1970's. The iron mines of Elba, most of which are long closed, were choice collecting localities for mineral enthusiasts, as early as the beginning of the 19th century. The pyrite specimens, such as this one, were especially prized. This brassy-colored specimen features many inter grown pyritohedrons up to 2.5 centimeters. This specimen is contacted on the lower sides but presents well and is not a detraction from the overall looks of the specimen. Ex. Howard Belsky collection.
P-091 Pinolite $45
Magnesite Deposit, Sunk, Hohentauern, Niedere Tauern, Styria, Austria
8.6 x 6.2 x 1.3 cm
Here we have an unusual specimen of two carbonate minerals, known as Pinolite, from Styria, Austria. Named for the white Magnesite crystals resembling pine kernels (hence the name), encased in a graphite-grey to almost black matrix of Dolomite.
H-080 Hemimorphite with Smithsonite $30
Dauntless Mine, Robinson District, White Pine County, NV
6.5 x 5.6 x 2.9 cm
Another mineral that you don't usually associate with Nevada is Hemimorphite. This specimen features Hemimorphite crystals up to 1.3 cm in size in a vug lined with sparkly crystals of Smithsonite.
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.
