A-108 Apophyllite on Stilbite $35 Momin Akhada, Rahuri, Ahmadnagar District, Maharashtra, India 6.8 4.3 x 3 cm. This specimen features a gemmy, radial spray of glassy, green-hued Fluorapophyllite crystals perched on a matrix of pale salmon-colored Stilbite crystals. These specimens were recovered during digging of several wells and are unique to this area.
B-145 Aquamarine on Schorl $45 Erongo Mountain, Erongo Region, Namibia 7 x 5 x 4 cm. A beautiful, sculptural cluster of pale Aquamarine crystals perched on cluster of trigonal crystals of Schorl Tourmaline from the Erongo Mountains of Namibia. This location has become very well-known for its Aquamarine and Schorl specimens. This specimen has a very good lustre. There is an area of contact on the bottom-rear of this specimen, but it does not detract any from the overall appearance of this piece.
Q-218 Quartz with Actinolite inclusions $85 Mega Horio, Serifos Island, Kykládes Prefecture, Greece 5.7 x 2.9 x 2 cm. After Laurium, the small island of Serifos (where iron has been mined since Roman times) is probably the most renowned mineral locality in Greece, especially for these world-class specimens of Quartz heavily included by the mineral Actinolite. These crystals are thought to have grown in irregular cavities encompassing the fibrous Actinolite which had formed earlier. These included Quartz specimens were first brought to market in quantity at the 1988 Tucson Mineral Show, being sold as Hedenbergite included Quartz. Since then, only occasional small lots have trickled out into the mineral market afterwards. These have always been highly sought after due to their rich color. Specimens of these amazing crystals are hard to come by these days.
G-057 Andradite Garnet $25 Stanley Butte, Pinaleño Mts, Graham County, Arizona 3 x 3 x 2 cm. An excellent cluster of well crystallized, greenish-brown Andradite Garnet crystals measuring up to 1.2 centimeters. The crystals on this specimen show a slight iridescence. This Garnet specimen was extremely hard to photograph and looks much, much more attractive in person.
G-100 Hessonite Garnet $85 Mana Mine, Barang-Turghao, Bajaur Agency, F.A.T.A., Pakistan 5.5 x 3.5 2.7 cm. A refreshing change from the endless supply of red, Spessartine Garnets on their white Albite are these colorful Hessonite Garnet specimens. This specimen features a translucent cluster of orange Hessonite crystals on a pale, sandstone-like matrix. This find is relatively new, first appearing in the fall of 2009. The largest of the Hessonite crystals measures 1 x 1 centimeters in size.
G-026 Grossular Garnet with Epidote, Diopside & Adularia $50 Tormiq Valley, Haramosh Mountains, Northern Areas, Pakistan 6.2 x 3.8 x 4.7 cm. A classic alpine-cleft-type mineral association.
H-011 Heulandite with Celadonite inclusions $25 Jalgaon, Maharashtra, India 3.5 x 4 x 3.5 cm. Here's one that in my opinion will be considered a classic in the future. Slightly curved and twisted Heulandite crystals included by Celadonite. These crystals have an extremely brilliant luster which many included minerals seem to lack.
C-141 Cuprian Adamite $45 Ojuela Mine, Mapimí, Durango, Mexico 8 x 9.8 x 4.9 cm. A striking specimen of the Copper-rich variety of Adamite from the historic Ojuela Mine in Mexico. The reddish-colored Limonite matrix combined with green color of the Cuprian Adamite makes for a very colorful specimen. The Copper-rich variety of the mineral Adamite is considered to be highly desirable by collectors and is much rarer than its yellow cousin Adamite.
Q-016 Quartz scepter crystal $25 Petersen Mountain, Washoe Co, Nevada (Hallelujah Junction) 7 x 5.8 x 4.5 cm Another strange one from a location that is noted for it's unusual Quartz crystals. I never cease to be amazed at the variations of scepter growth that Petersen Mountain yields. The termination of this crystal crenellated and has a slight depression.
L-006 Lepidolite ps. after Tourmaline $15 Itinga, Minas Gerais, Brazil 3.5 x 2 x .9 cm. A very lustrous Tourmaline that has been partially replaced by Lepidolite. These specimens are “old timers” that were found in the 1970's.
L-034 Lepidolite with Topaz $60 Virgem da Lapa, Minas Gerais, Brazil 10.5 x 7 x 4.4 cm. What we have here is more of a Lepidolite specimen than it is a Topaz specimen. This specimen consists of numerous well-formed crystal of Lepidolite that measure up to 3 x 3 centimeters and are dusted with a coating of Muscovite and accented by a 3 centimeter crystal of Topaz. The Topaz crystal has a little wear on the lower left corner of the crystal. I think that it is trivial as the main feature of this specimen are the Lepidolite crystals.
F-200 Fluorite with Chalcopyrite inclusions $15 Fronhau, Saxony, Germany 4.8 x 3.3 x 2 cm. An example of multi-colored Fluorite from Germany. This specimen features yellow and purple,color-zoned crystals up to 1 centimeter in size. The Fluorite crystals on this specimen are heavily included by tiny crystals of Chalcopyrite.
Q-180 Quartz $40 Getchell Mine, Adam Peak, Potosi District, Osgood Mts, Humboldt County, NV 11.5 x 7.6 x 8.5 cm. One of the great things about Nevada besides the abundance of Gold, other metals, Barite, et al; is the mind-boggling number of localities where you can collect Quartz crystals. This fist-sized crystal hails from the northwestern corner of Nevada and exhibits skeletal growth on its front face. A good locality piece suitable for any collector of Quartz or Nevada minerals.
Q-208 faden Quartz with Chlorite $40 Goschenen Valley, Uri, Switzerland 5.5 x 4.3 x .8 cm This specimen of clear Quartz exhibits a features that Alpine Quartz specimens are noted for. “The Faden” growth habit (German for "string", in reference to the line running down the center of the crystal) habit. The upper portion of this crystal is liberally coated by the mineral Chlorite. The Chlorite accentuates the physical features of the crystal growth.
AH-028 Analcime
with Synchysite $75 Poudrette Quarry, Mont Saint-Hilaire, Québec, Canada 10 x 5 x 4.5 cm. This large specimen, upon first glance, appears to be a rather typical-looking cluster of Analcime crystals, but this specimen is more than that. The dark gray region is composed of hundreds of 0.5 millimeter disk-shaped crystals of the rare mineral Synchesite-(Ce). (Ce is the symbol for the rare-earth element Cerium, for you non-chemists out there.) Although some are naked-eye visible, the Synchesite crystals are better viewed with a loupe or a microscope which also reveals a sprinkling of minute Pyrite crystals, especially along the edges of the Synchesite discs.
H-021 Heulandite with Celadonite inclusions $40 Jalgaon, Maharashtra, India 8 x 6 x 3.7 cm. Here's an example of a mineral specimen that in my opinion will be considered a classic in the future. This matrix specimen features slightly curved and twisted Heulandite crystals included by the mineral Celadonite. These crystals have a brilliant luster, which many included minerals seem to lack.
E-022 Epidote and Quartz $25 Fazenda Rubinho Pimenta Claim, Capelinha, Minas Gerais, Brazil 3.9 x 2.4 x 2 cm. When one thinks of Epidote, one often overlooks the good quality specimens that can be found in Brazil, such as the one presented here. This columnar Epidote specimen features several double-terminated Epidote crystals hitchhiking on the side of its termination, as well as a transparent double-terminated 2.5 cm. Quartz crystal, which encapsulates a small bloom of Epidote. A striking example of Epidote which would enhance anyone's collection.
T-126 Schorl Tourmaline $17.50 Santa Cruz, Sonora, Mexico 5 x 4 x 2 cm. This triangular cluster of Schorl crystals exhibits a very lustrous, velvet-like sheen, and in fact is sometimes referred to as velvet Tourmaline. Once abundant in the old days, these striking crystals of Schorl are not easy to find these days. This specimen would be a fine addition to any collection.
A-040 Apophyllite with Stilbite $20 Jalgaon, Maharashtra, India 5 x 5 x 5 cm. What at first appears to be your run-of-the-mill Fluorapophyllite from India, is actually quite unusual. What makes this specimen so unusual is that the terminations of the Fluorapophyllite crystals are slightly inverted and also exhibit a hoppered-like crystal growth. The Fluorapophyllite crystals exhibit a very bright lustre. Also present on this specimen are small blades of white-colored Stilbite. L-026 Limonite pseudomorph after Pyrite $17.50 Extertal, Westphalia, Germany 3 x 3.7 x 2.3 cm. Here we have a mound-like specimen of interpenetrating crystals of the mineral Pyrite that have been replaced by Limonite. The largest crystal on this specimen measures 1.7 centimeters. A classic and hard to find German specimen.
M-026 Malachite on Barite $15 Thasos Island, Kavála Prefecture, Macedonia, Greece 3 x 4 x .9 cm. This is not your typical Greek mineral specimen. This Barite crystal is draped with a carpet of light green crystals of Malachite. A good locality piece for a good price.
F-185 Albite variety Pericline with Epidote $17.50 Capelinha, Minas Gerais, Brazil 4.5 x 3.5 x 3.5 cm. This blocky Pericline-twinned Albite crystal was in my Feldspar collection. It is hollow in the center of the main crystal. Accenting one side of the specimen are many small crystals of Epidote.
C-109 Cerussite $17.50 Mibladen, Midelt, Khénifra Province, Morocco 3.1 x 2.4 x 2.1 cm. A pair of well-terminated and lustrous crystals of the Lead mineral, Cerussite. The bottom of this specimen features a pockmarked texture. Cerussite specimens from Morocco were at one time easier to find, but these days one has to look a lot harder to find one.
A-024 Arsenopyrite with Quartz $17.50 Yaogangxian Mine, Chenzhou Prefecture, Hunan, Central South Region, China 4.2 x 2 x .8 cm. A very interesting crystal that has a great luster on the top crystal face and interesting iridescent patina covering the remainder of the crystal with a mass of Quartz crystals covering the upper portion of the crystal.
C-102 Celestite with Sulphur SOLD Machów Mine, Tarnobrzeg, Podkarpackie, Poland 5.5 x 5 x 4.1 cm. A beautiful, chunky, cluster of Celestine crystals from the famous Sulfur mines of Podkarpackie, Poland. This well-formed specimen when illuminated by SWUV light shows a strong whitish-yellowish-green fluorescence and exhibits a pleasing light-green phosphorescence. A great specimen for anyone's mineral cabinet, especially collectors of fluorescent mineral specimens.
F-098 Fluorite with Calcite & Barite SOLD Moscona Mine, Solís, Gijón, Asturias, Spain 10.2 x 7 x 4.4 cm. A classic combination of gemmy Fluorite with Calcite, Barite and saddle-shaped Dolomite crystals. A top-notch Spanish Fluorite that would be a fine addition to any collector's mineral cabinet. Fine, aesthetic specimens from this location are becoming increasingly harder to find these days.
T-152 Topaz with Schorl SOLD Erongo Mountain, Erongo Region, Namibia 4 x 2.5 x 2.3 cm. When one thinks of Erongo, the first thing that comes to mind are the plethora of Aquamarines and world class Fluorite specimens that this modern-day classic mineral location has produced. Erongo Mountain, over the years has produced some great Topaz as well. This Topaz shows just a slight blush of blue when viewed down the c-axis of the crystal, especially from the bottom. The terminal faces of this Topaz crystal are covered with dozens of needle-like Schorl crystals. While there are several corners on the bottom of the crystal that have some dings, the largest one appears to have happened in situ as its surface exhibits several small growth hillocks suggestive of regrowth.
P-070 Pyromorphite SOLD Huari-Huari Mine, Seranía Huarihuari, Potosí Department, Bolivia 7 x 6.4 x 3 cm. On a worldwide scale, these Pyromorphite specimens from Boilvia are not the best, but for the location, they are quite interesting and unique. This material is something that is very rarely offered on the open market. This specimen has many fine, sharp and somewhat lustrous, prismatic, green and yellow crystals of Pyromorphite sitting atop an oxidized matrix. These are very well formed crystals and are not skeletal or hoppered as is often the case with Pyromorphites from other locations. This specimen was collected in May of 2009.
T-224 Tourmaline var. Schorl SOLD Dara-i-Pech, Kunar Province, Afghanistan 8 x 6 x 5 cm. Here we have a chunky crystal of Schorl with overgrowths of Albite. The sides of this heavy crystal are beautifully striated and highly glossy. The top of the crystal has a nicely modified termination with six alternating glossy-and-matte-finish faces surrounding the top triangular face. Many of the terminal faces also show interesting growth hillocks.
A-109 Analcime with Natrolite SOLD Robertson Pit, Dayton, Mason County, WA 8.1 x 5 x 3.1 cm. This specimen consists of clear to translucent crystals of Analcime measuring up to 1.2 centimeters on a matrix of Eocene pillow basalt. Accenting the Analcime crystals is a 2.6 centimeter spray of Natrolite crystals. This specimen was collected in the 1990's by prolific digger John Cornish whom amongst other things brought us the peach-colored Heulandite crystals on snow-white Mordenite from Idaho. Most recently all of those stunning Crocoite specimens from Tasmania, Australia.
C-188 Calcite SOLD Santa Eulalia District, Mun. de Aquiles Serdán, Chihuahua, Mexico 12 x 5.8 x 6 cm. This specimen of Calcite features many soccer-ball shaped crystals that culminate in a spire on the right side of the specimen. This calcite specimen has an excellent lustre and a rich brown color on one side with the backside being closer to grey-black in color. This specimen shows very well the diversity of the mineral Calcite.
T-209 Dravite Tourmaline on Magnesite SOLD Brumado, Bahia, Brazil 3 x 1.5 x 1.5 cm. This reddish-brown specimen of Dravite Tourmaline is apparently a floater. In addition to several very clear Magnesite crystals, this specimen has a sugary coating of microcrystals.
F-104 Fluorite SOLD Denton Mine, Hardin County, IL 6.5 x 7.2 x 2.3 cm. A very clear crystal of purple-blue Fluorite that has been partially etched. A really neat Fluorite specimen if you ask me. This specimen has wear on several of the corners and taking this into consideration, I have reduced the price accordingly. |
