AD-097 Opal $60 Yowah Opal Field, Queensland, Australia 7.4 x 6.3 x 3 cm. This striking specimen of “Yowah Nut” Opal consists of an ironstone nodule that is permeated by Opal of many different colors that it makes for a very colorful and aesthetic specimen. Photos do not do this specimen justice, when you hold it in your hands you will be amazed by the contrast of colors that this specimen has. It makes a great educational piece as well, showing in great detail how these “nuts” are formed.
F-098 Fluorite with Calcite & Barite $30 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 $75 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.
B-145 Aquamarine on Schorl $40 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. Demand for these have always been highly sought after due to their rich color. Specimens of these amazing crystals are hard to come by these days.
T-224 Tourmaline var. Schorl $35 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.
C-141 Cuprian Adamite $30 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.
AD-098 Opal $60 Yowah Opal Field, Queensland, Australia 7.4 x 6.3 x 3 cm. This striking specimen of “Yowah Nut” Opal consists of an ironstone nodule that is permeated by Opal of many different colors that it makes for a very colorful and aesthetic specimen. Photos do not do this specimen justice, when you hold it in your hands you will be amazed by the contrast of colors that this specimen has. It makes a great educational piece as well, showing in great detail how these “nuts” are formed.
M-053 Lepidolite $35 Ouro Fino Pegmatite, Coronel Murta, Minas Gerais, Brazil 9.2 x 7.1 x 3.5 cm. A bi-colored Lepidolite specimen. The contrast of colors and textures makes for a striking specimen and has an almost surreal look under good light. One more example of the diversity of Brazil's pegmatites. An extremely fine example of this material was pictured (page 600) in the book Minerals and Precious Stones of Brazil that was published in 2010.
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.
C-188 Calcite $15 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 $15 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.
E-022 Epidote and Quartz $20 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.
F-104 Fluorite $25 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.
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-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-102 Celestite with Sulphur RESERVED 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.
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.
T-156 Elbaite Tourmaline SOLD Stak Nala, Skardu District, Baltistan, Pakistan 5.3 x 1.4 x .9 cm. In the past six or seven years, little of note has been found in the Tourmaline deposits of Stak Nala. These lipstick-like Tourmalines were found in the fall of 2007 and are quite different than the multicolored Tourmalines for which this location gained notoriety. When strongly backlit, the dark area of this bent, rehealed and slightly twisted Tourmaline crystal exhibits an olive-brown hue on its edges.
T-130 Tourmaline
variety Elbaite SOLD Dara-i-Pech, Kunar Province, Afghanistan 2.2 x 1.3 x 1.2 cm. This specimen is a good example of the diversity of Tourmalines that can be found in Afghanistan. This bicolored Tourmaline crystal exhibits a cat's-eye like chatoyance and is double-terminated.
C-178 Calcite SOLD Brushy Creek Mine, Reynolds County, Missouri 5 x 7 x 3.5 cm. What we have here is not your usual Brushy Creek Mine Calcite specimen. It consists of a pair of light gray crystals that have been overgrown with lustrous, clear Calcite with a phantom right below its termination. Quite different from the opaque, gray crystals coated with iridescent Chalcopyrite that this famous locality is most noted for. In its day this mine was a prolific producer of specimens. I haven't seen any new material from this mine in quite a long time.
C-179 Calcite SOLD Brushy Creek Mine, Reynolds County, Missouri 7 x 3.5 x 2.6 cm. What we have here is not your usual Brushy Creek Mine Calcite specimen. It consists of a light-gray single crystal that has been overgrown lustrous, clear Calcite with a phantom right below its termination. Quite different from the opaque, gray crystals coated with iridescent Chalcopyrite that this famous locality is most noted for. In its day this mine was a prolific producer of specimens. I haven't seen any new material from this mine in quite a long time.
Q-339 Quartz SOLD White Rock Quarry, Horsnell Gully, South Australia, Australia 6.3 x 4.6 x 2.4 cm. This is a very aesthetic example Quartz. This glassy, transparent Quartz crystal has many “hitchhiker” crystals attached to it. This is due to several generations of growth. The Quartz crystal is double terminated with an unusual termination on the upper part. This specimen is much clearer than it appears in the photograph.
W-021 Wavellite SOLD Mauldin Mountain, Montgomery County, Arkansas 5 x 4 x 3.5 cm. This sparkling, grass-green specimen features two balls of Wavellite on a thin carpet of the same. This locality is now defunct and it is getting harder and harder to find good examples of this material.
