Wire Silver on matrix

Locality: Kongsberg, Buskerud, Norway

Specimen Size: 4.5 x 2.7 x 2.3 cm (miniature)
Silver Wire: 2.2 cm long


ex.  Brett Keller


One of the true classics in the mineral world is Kongsberg Silver. These are the most famous specimens of Silver extant with their legendary wire formations. It is difficult to find matrix specimens from Kongsberg, let alone pieces with good aesthetics, as many of them can be "lumpy" or can simply have less than pleasing form. This piece however has fine aesthetics with a fairly thick, striated, "rope"-like wire of Silver measuring 2.2 cm jutting out of the matrix. The wire itself has that classic rich patina that is associated with old Kongsberg Silvers and it's very attractive from either side. The matrix, interestingly, has one noteworthy crystallized Quartz prism that is partially frozen in place along with smaller Silver wires and exposed massive golden metallic Pyrite. A fantastic miniature with fine aesthetics from this incredibly historic mining district.

Tourmaline (multicolor polished slice) from Anjanabonoina pegmatites, Ambohimanambola Commune, Betafo District, Vakinankaratra Region, Antananarivo Province, Madagascar [./wwmix518/wwmix51802a.JPG] Tourmaline (multicolor polished slice) from Anjanabonoina pegmatites, Ambohimanambola Commune, Betafo District, Vakinankaratra Region, Antananarivo Province, Madagascar [./wwmix518/wwmix51802b.JPG]

Tourmaline (multicolor polished slice)

Locality: Anjanabonoina pegmatites, Ambohimanambola Commune, Betafo District, Vakinankaratra Region, Antananarivo Province, Madagascar

Specimen Size: 4.7 x 3.7 x 2.2 (miniature)


A classic polished slice of multicolor or polychrome Tourmaline from Anjanabonoina. For years these specimens were labeled as Liddicoatite, but most likely there are more than one species present, and possibly as many as three or four including Fluor-liddicoatite, Schorl, Elbaite, or Fluor-Elbaite. Honestly it's impossible to know which species are present without x-ray diffraction and Wavelength-dispersive spectroscopy analysis. With that said, these polished slices from Madagascar are some of the most iconic examples of Tourmaline from anywhere as no two are ever the same, and they can vary widely in their form and coloring. This particular piece features a dark "core" which grades into different shades of lilac / purple and then transitions into a thin area of green and colorless banding that gives way to beautiful blue zones on the "rind". I've seen many of these slices over the years, but I bought this one because I've never seen this particular pattern and mix of colors as there are in this slice. Blue is RARE from Madagascar in my experience, and many of the slices I've seen over the years are typically dark and "muddy", but this one is crisp and notably eye-catching. As an aside, it should be noted that as of 2011, Liddicoatite is no longer a species. The type material is actually F-dominant, and it appears that all Liddicoatites may be F-dominant, so Liddicoatite is now Fluor-liddicoatite.

Chrysoberyl Twin on Quartz (rare matrix specimen!)

Locality: Espirito Santo, Brazil

Specimen Size: 3.3 x 2.8 x 1.6 (miniature)


From a find at the end of 2017. Some of the most classic Chyrsoberyl specimens in the world are those from the small state Espirito Santo in southeastern Brazil. These specimens exhibit some of the most recognized and celebrated crystal habits for Chrysoberyl extant in the form of beautiful "sixling" and "heart-shaped" twins. This piece is an exceptionally rare MATRIX specimen of Chrysoberyl from Espirito Santo as it features a fine, undamaged, sharp, lustrous, translucent, yellow-green colored "sixling" (more properly "trilling") twin of Chrysoberyl aesthetically sitting atop a sharp, lustrous, translucent, partial smoky gray Quartz crystal. I immediately thought the piece resembled a snail when I first saw it, and the fact that the Chrysoberyl is complete all the way around is significant.  Additionally, the twin is notably robust and stout, not flattened like many of the Chrysoberyls we've seen from this locality over the years.  This piece is most certainly a fine large thumbnail / toenail for which most collectors do not have a good representation in their collections, ESPECIALLY on matrix. One of my favorites that I've seen from Espirito Santo.

Chrysoberyl Twin

Locality: Espirito Santo, Brazil

Specimen Size: 2.0 x 1.6 x 0.6 (thumbnail)


From a find at the end of 2017. Some of the most classic Chyrsoberyl specimens in the world are those from the small state Espirito Santo in southeastern Brazil. These specimens exhibit some of the most recognized and celebrated crystal habits for Chrysoberyl extant in the form of beautiful "sixling" and "heart-shaped" twins. Here we have a lovely "heart-shaped" twin of Chrysoberyl exhibiting fine, sharp, lustrous faces with a beautiful, gemmy yellow-green interior. The piece is complete all around and actually has an unusual hollow cavity on the reverse side, possibly where another Chrysoberyl once grew, or possibly something like a Quartz crystal that dissolved away. A great example of these classic, iconic and sought after specimens.

Chrysoberyl (Unusual Twin)

Locality: Espirito Santo, Brazil

Specimen Size: 1.9 x 1.1 x 0.9 (thumbnail)


From a find at the end of 2017. Some of the most classic Chyrsoberyl specimens in the world are those from the small state Espirito Santo in southeastern Brazil. These specimens exhibit some of the most recognized and celebrated crystal habits for Chrysoberyl extant in the form of beautiful "sixling" and "heart-shaped" twins. This piece is a rather unusual twin that is actually a combination of two partial "sixling" twins which are growing along the prism of an elongated Chrysoberyl crystal to create a "star" or "cross-shaped" specimen. I've seen hundreds of Chrysoberyls from Espirito Santo over the years, but THIS one stands out as unique, as I have never seen a piece with this particular habit / form. The faces are lustrous and well-formed and the piece glows with a lively yellow-green hue when backlit. We've done our best to photograph the piece from all sides to illustrate its distinctive shape. This one is certainly a one-of-a-kind specimen, and a great pickup for anybody who collects gem crystals, thumbnails, Brazilian minerals or interesting morphologies.

Opal replacing Wood

Locality: Java, Indonesia

Specimen Size: 3.3 x 1.1 x 1.0 cm (miniature)


A newly mined piece of this exciting Precious Opal replacing Petrified Wood from Java, Indonesia. This piece features pockets of highly colorful Precious Opal which show bright color flashes of red, gold, orange, yellow, green and purple in brownish-black Petrified Wood. The specimen is slightly polished / rounded to help the Opal really shine. The Opal honestly doesn't need a strong light to show off the color, and it's really pretty when viewed up close. This piece came to us direct from a friend who travels to Indonesia to buy material. It's very worthwhile for collectors becuase it's not just a mineral specimen, nor a gem specimen nor a fossil, but a combination of all three. Weight is 37.90 carats.

Opal-AN (Hyalite Opal) (fluorescent)

Locality: Zacatecas, Mexico

Specimen Size: 3.6 x 3.2 x 2.2 cm (miniature)


A beautiful specimen of the fairly new Hyalite Opal (now properly called Opal-AN) that started trickling out of central Mexico at the end of 2013 according to reports. Typically, Hyalite is colorless and not terribly eye-catching, but these new Mexican specimens have really given collectors an amazing impression of how fine and attractive this material can be. With that said, this piece shows a lovely greenish-yellow hue in indoor lighting, but it gets better. If you take it in the sun (even in a shaded area), you will notice a natural daylight fluoresence that is not commonly observed in Opal, but you can take it one step further because under both SW and LW UV light, the fluorescence is about as electric and intense as it gets for any mineral.  Additionally, there are some small areas of multicolor iridescence that can be seen in a few of the "balls", which is rare in my experience with the material.  An amazingly bright yellow-green glow can be seen that is almost unmatched in fluorescent minerals. It has been said that gamma spectroscopic data indicates that this brilliant color is possibly attributed to the presence of uranium in the form of a uranyl (UO2 2+) molecule! I suppose it's not terribly surprising that uraniferous Opal would have this kind of fluorescence, but it's certainly rare and very attractive. This particular piece features several gemmy to translucent, globular "spheres" of Opal-AN on host rock matrix. The color ranges from a soft greenish-yellow to virtually colorless. They look like little beads of jelly. I have seen similar specimens from Erongo, Namibia, but the Mexican pieces have larger "balls", a richer coverage of the Opal itself, and stronger color is some cases. This is the kind of material that would be perfect for anybody who appreciates Opal as a species, and definitely should be on the radar of any fluorescent mineral collector! From what I'm told the find was incredibly limited, and if you want one, get one now as they are already scarce on the market. It should be noted that Hyalite is not a species, nor a variety of Opal, as the material is now called Opal-AN (the listing on mindat.org states that "The "A" in the name stands for amorphous; the subscript "N" is to imply its structure is network-like similar to silica glass; however, it still contains about 3-8% water"). Lastly, the exact locality for this material has not been disclosed, or possibly is not known by those who brought it to the market, so I'm simply labeling it as Zacatecas, Mexico.

No. WWMIX51810 - $ 800.00

Spinel (large "floater" crystal)

Locality: Mogok Township, Pyin-Oo-Lwin District, Mandalay Region, Myanmar (Burma)

Specimen Size: 3.7 x 3.3 x 2.6 cm (miniature)


The area around Mogok has been the source of the finest crystallized Spinels in the world for decades, but the vast majority of crystals are under 1 cm. Most people are familiar with the classic red Ruby Spinel crystals from this area, but with the exception of yellow, Spinels come in literally every color of the rainbow. Recently we were able to obtain a handful of large Spinel crystals from recent mining in Mogok, and they are some of the more impressive examples of crystallized Spinel that we've handled. I was impressed to see specimens of this size with such excellent crystallization, unique coloring and fine quality. Typically, Spinels will become incredibly distorted, dull and unappealing when they are found in larger crystals, but this piece is a superb example of a large Spinel as it is notably sharp, lustrous, and well-formed! It's not "lumpy" or muted like so many of this size can be. It has very smooth octahedral faces with a glistening almost "wet" luster and a beautiful color combination of a grape purple with pink tones swirling throughout. When the crystal is backlit, it shows a gorgeous reddish or golden pink hue on the edges. To top it off, the piece is a complete "floater" with no point of attachement whatsoever. Spinel is one of those gem crystal species which most collector do not have a good example in their collection and a piece like this is certainly better than the vast majority we've seen over the years when compared to crystals of equal size.

Quartz "cast" after Calcite

Locality: Crystal Cave, Canyon Creek, Ouray County, Colorado

Specimen Size: 7.2 x 4.2 x 3.2 cm (small cabinet)


These specimens are some of the most classic Quartz after Calcite "casts" from any world locality. They are sometimes called epimorphs or perimorphs depending upon who you ask. With that said, this specimen is a fantastic example showing the perfect scalenohedral form of the previous Calcite crystals which were replaced, being coated by very small, almost "sugary", gem quality, colorless Quartz crystals. The Calcite crystals were then dissolved away by a solution that entered the pocket at a later date, leaving behind only the Quartz crystal "crust". A wonderful specimen from a district that produced some of the most classic "casts" from all of Colorado.

Rhodochrosite with Quartz

Locality: Champion Mine, near Lake City, Cinnamon Pass, Park District, Hinsdale County, Colorado

Specimen Size: 9.0 x 5.8 x 4.5 cm (small cabinet)
Largest Crystal: 3 mm


The Champion mine is well known to Colorado collectors for producing some attractive Rhodochrosite, but specimens are seldom available on the market. This piece features dozens of sharp, beautiful pink color rhombohedra of Rhodochrosite forming semi-"rosette"-shaped groups associated with and sitting on Quartz matrix. You can see a bit of sparkling golden Chalcopyrite dotting the Rhodos for a really nice touch. The largest crystal of Rhodochrosite measures 3 mm. This is certainly an above average specimen, not to mention that it's nearly a full-sized cabinet display piece, which is rare from this hard to find locality in southwestern Colorado.

Rhodochrosite

Locality: Zanett Tunnel, Grizzly Bear Mine, Bear Creek Canyon, Ouray County, Colorado

Specimen Size: 4.7 x 3.3 x 1.0 cm (miniature)


ex.  Brett Keller and Robert E. Jenkins II


The Zanett tunnel is named after the family that owns the Grizzly Bear mine. Rhodochrosite specimens from this mine are among some of the most sought after San Juan Rhodochrosites by Colorado collectors. This specimen hosts very good-sized (for the locality), sharp, lustrous, well-formed, rich pink colored rhombohedrons of Rhodochrosite which have formed into a crystallized "plate" that is actually free of matrix. The largest Rhodochrosite crystal measures 6 mm. I can't see any damage except around the periphery where the piece was removed from the pocket wall. A beautiful miniature-sized specimen of this classic material. Very good quality, eye-catching and rare on the market. The piece comes from the collection of Brett Keller with a dealer label from Jasun McAvoy and an old label from the Robert E. Jenkins II collection.

Fluorite ("phantom" crystals) with Microcline (var: Amazonite)

Locality: Purple on Blue Pocket, Blue Smoky Clain, Florissant, Teller County, Colorado

Specimen Size: 2.6 x 2.3 x 1.7 cm (thumbnail)
Largest Crystal: 1.5 cm


Here we have an attractive thumbnail-sized Fluorite specimen from the one of the Dorris family claims. The piece hosts a cluster of sharp, well-formed, gemmy, cubic crystals of Fluorite measuring up to 1.5 cm and associated with small bits of blue-green Amazonite. The Fluorites show beautiful "phantom" zoning and when they're backlit they show a lovely purple color on the exterior and an unusual rich reddish to golden-brown hue in the "cores" of the crystals. This particular color combination is rare in Fluorite from any locality in my experience. The piece is undamaged on the front / display side, and shows and unusual cavity on the back, that might be a partial "cast" after a preexisting mineral like Quartz. Good thumbnails of Fluorite or any species from the Pikes Peak Batholith are hard to find because the nature of the pockets doesn't really produce them.

Barite ("phantom" crystals)

Locality: 121 Stope, 1250 Level, Black Cloud Mine, Leadville, Lake County, Colorado

Specimen Size: 3.7 x 3.2 x 1.7 cm (miniature)
Largest Crystal: 8 mm


The Black Cloud mine is renowned for its sulfide specimens, but it has also produced the classic golden Barites for which the Leadville Mining District is known. Here we have a beautiful miniature specimen comprising bladed, sharp, gemmy, lustrous Barite crystals with that classic golden color sitting on matrix. Upon close inspection one can see that the crystals actually show classic, beautiful internal "phantoms". This specimen came out in the late 1970s or possibly early 1980s. This area has produced some of the finest Barites from Colorado, and these specimens are highly sought after by Colorado collectors for the attractive color and form.

Ferrokesterite (exceptionally superb twin) on Andorite

Locality: San Jose Mine, Oruro City, Cercado Province, Oruro Department Bolivia

Specimen Size: 3.7 x 2.5 x 2.3 cm (miniature)
Ferrokesterite Twin: 1.8 cm across


From the amazing discovery from 2004, here is one of the finest examples of Ferrokesterite in the world. I personally acquired the best of these specimens in Bolivia and brought them into the country along with the world's finest Andorite crystals. Initially we thought these Ferrokesterite specimens were twinned crystals of Stannite. Virtually all of the pieces from the find were sold as "Stannite", but it turns out that they are the much rarer dimorph, Ferrokesterite! This species is truly only known from a handful of localities in the world, including the Type Locality at the Cligga Mine in Cornwall, England. The Bolivian specimens are tremendously superior to the Cornish pieces in every sense. They are notably larger with incredibly well-pronounced crystals (featuring beautiful penetration twins), and some are even associated with Pyrite, Zinkenite and Andorite. For reference, these Ferrokesterite were analyzed and confirmed by Bob Downs of the University of Arizona. PLEASE READ the FULL STORY that I wrote several years ago on these pieces, at this link here. It should be noted that the specimens from this disovery are undoubtedly the world's finest Ferrokesterites, and in great limited supply. This specimen came out nearly fifteen years ago, and virtually nothing has come out of the ground in quite some time.

This is a very rare MATRIX specimen featuring a penetration twin of Ferrokesterite measuring 1.8 cm at its longest dimension sitting on bladed/layered Andorite crystals and thin "needles" of Zinkenite. The Ferrokesterite has excellent crystal form with a silvery-black exterior and very good luster for the species. The Andorites show that classic "gun metal" hue and are notably well-crystallized with the classic "layered" growth. Together with the Zinkenite, they comprise a very rare combination/association specimen. I have only seen three pieces of Ferrokesterite on Andorite like this. This particular piece is the best and most aesthetic specimen I have seen from this locality, and has remained in my personal Bolivian collection for many years. To have the best of any species is certainly rare, but when it's combined with the fact that the crystals are superb penetration twins on matrix, makes it all the more enticing. Another significant feature of the piece is that this is an incredibly rare sulfide, and the crystals aren't micros! You can clearly see them with the naked eye, which is remarkable when one is talking about such a rare species (it's only found in about 12 places in the world). Perhaps the most important aspect of the piece is that it is nearly a complete "floater"!! It's literally crytallized nearly all the way around with only a tiny contact on the bottom, but the rest of the specimen is undamaged! I will reiterate that this association is extremely rare, and to find a piece with such superb aesthetics is astounding. For anybody who has ever wanted a superb piece of this remarkable material from this famous, historic, 500+ year old mine, this is arguably the finest matrix example that I have had to offer.

Uvarovite

Locality: Saranovskii Mine (Saranovskoe), Saranovskaya Village (Sarany), Gornozavodskii area, Permskaya Oblast', Middle Urals, Urals Region, Russia (TYPE LOCALITY)

Specimen Size: 8.4 x 4.1 x 2.7 (small cabinet)


ex.  Kay Robertson


The great chrome mine at Sarany has produced some of the most colorful and impressive "Alpine-type" Russian mineral specimens, including some of the finest Uvarovite crystals in the world. This specimen features hundreds of Uvarovite crystals with high luster and intense emerald-green color on chromite matrix. The species was named after Count Sergey Semeonovich Uvarov, the former president of the Academy of St Petersburg. These specimens have become increasingly difficult to obtain in recent years, and are certainly recognized as some of the finest in the world. We have photographed the crystals with a macro lens to better illustrate their quality. A very worthwhile small cabinet sized specimen of this classic material. From the collection of Kay Robertson (#12215). Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).

"Rainbow" Andradite Garnet

Locality: Kohse Mine, Tenkawa village, Yoshino-gun, Nara Prefecture, Kinki Region, Honshu Island, Japan

Specimen Size: 1.0 x 0.8 x 0.5 cm (thumbnail)


A wonderful well-formed dodecahedral group of the famous "rainbow" Andradite Garnets from the famous Kohse Mine. At first glance, these crystals appear to have some kind of artificial coating, but it turns out that the brilliant iridesence is 100% natural! There are actually a few places in the world where rainbow Andradite is found. But the Japanese specimens are the most desirable and sought after. The colors exhibited can range from warm reds, oranges and pinks to cool blues and greens. These crystals are rare on the market now, even though they were fairly easy to get a decade ago. This particular piece shows notably sharp and very smooth faces with a beautiful mix of pink, yellow, orange, lialc, blue and green metallic flashes on the surface of the faces. The best aspect of the piece is that it doesn't have the typical flat circular "water spots" that can ruin the appearance, instead the surface of the faces are unblemished on the display side. The piece is complete on the front, contacted on the back, but it's still a very attractive representative example of this rare material. If you're a Garnet collector, you should have one of these in your collection. They're so beautiful and unique for a commonly known species. It should be noted that the locality is completely off limits to collectors, and NO MORE specimens will be coming to the market, so if you want one of these crystals, don't miss out on this opportunity, because they will just become harder to get as the years go on.

Petrified Wood (rare color) with Banded Agate

Locality: Petrified Forest, Gokwe South, Midlands, Zimbabwe

Specimen Size: 14.0 x 9.8 x 4.2 cm (cabinet)


We don't sell a lot of fossilized material, but we found these at the Tucson Show and couldn't pass them up due to their unique and alluring color. Petrified wood is found in a wide range of colors, but green is certainly rare worldwide. I'm told that the color is caused by nickel content, and it's not dyed, as you can clearly see solid green patches on the back (unpolished side) of the piece. The form of the original tree is clearly seen and well-preserved. If you look closely, you can actually see patches of beautiful soft lilac colored banded Agate which has filled in some of the open vugs in the wood! This is INCREDIBLY rare in our experience with this material, and certainly makes the piece more desirable for collectors. For a final touch, the patches of Agate actually fluoresce a bright green hue under SW UV light. The species is Woodworthia sp., which is a primitive conifer from the Triassic epoch dating back approximately 200 million years. Beautiful material and certainly different from your run of the mill petrified wood.
