Wulfenite (fluorescent) with Galena, Calcite etc.
stock #15.1-881
Touissit, Touissit-Bou Beker Dist., Jerada Province
Oriental Region, Morocco
8.6 x 7.7 x 5.3 CM (cabinet)
price: $380
Early summer 2021

A very unusual and complex specimen from Touissit that is a fine illustration of lead secondary mineral formation. The core of this piece is a highly etched and partly dissolved mass of Galena, showing alteration to several other minerals. Around that is a mass of Calcite and Dolomite that are the matrix of several generations of well-crystalized Wulfenite. The oldest are completely encased in translucent Calcite, the most recent are smaller, more lustrous and vividly fluorescent in long-wave UV. The Galena was of course the source for the lead that was released as it was affected by acidic conditions and which then formed the Wulfenites. Most of the many Wulfenites are complete and perfectly undamaged but there are a few with chipping damage that are not distracting and are almost invisible in the mass of the specimen. Touissit is an amazing locality, though over shadowed by the more famous Tsumeb. It too has incredible variety and complexity to its minerals. This is a very rare fluorescent Wulfenite with just the youngest crystals responding lemon-yellow.

Spessartine - etched gem crystal
stock #21.FC-007
Navegadora Mine, Penha do Norte, Conseheiro Pena, Doce Valley
Minas Gerais, Brazil
3.8 x 2.8 x 2.5 CM (miniature)
price: $1600
Early summer 2021

A very lustrous, complete Spessartine crystal with a tiny sliver of Albite attached. From the unique and world famed Navegadora claim in Minas Gerais, this is completely etched and recrystallized with fine geometric structures on all sides. In person this looks like red glass. Fully gemmy and transparent, when backlit the entire piece glows a brilliant red. In super condition, a very close exam finds only a very small rough edge that is not seen from most any angle, this is essentially a perfect floater. The etching has gone so far as to create small geometric cavities and tunnels through the mass of the Garnet. A modern classic, 30.2 Grams and all gem.

Wavellite
stock #21.1-231
La Caridad Mine, La Caridad, Nacozari de Garcia Municipality
Sonora, Mexico
8.7 x 3.6 x 2.8 CM (cabinet)
price: $140
Early summer 2021

A nearly pure Wavellite specimen with minimal matrix, the Wavellite is in fibrous layers surrounding an open vug. The vug surface is a lemon-yellow carpet of botryoidal Wavellite that with good lighting has a wet-look luster. An unusual style and habit that is unlike most any other Wavellite in the entire world. From long ago finds at the La Caridad Mine, we have not seen any new material available for decades, only from older collections like this piece.

Bismuthinite with Ferberite and Fluorite, Cosalite etc.
stock #20.FC-117
Kara-Oba W Deposit, Betpakdala Desert
Karaganda Region, Kazakhstan
6 x 2.9 x 2.3 CM (cabinet)
price: $3700
Early summer 2021

This would be a world class Bismuthinite from anyplace and is exceptional from Kara-Oba. The addition of a complete, doubly terminated Ferberite adds a great balance, and the coatings of tiny bright purple Fluorite puts this piece in a class by itself. With good magnification several Cosalite sprays of metallic needles are noted, along with flattened Quartz crystals. In excellent condition, the Fluorite druse covers some faces of the Bismuthinite as well as the Ferberite, adding a nice sparkle in person. The Bismuthinte crystals are up to 6 CM tall and have a fine metallic patina seen on one side. Bismuthinite is not normally an attractive mineral but this is a very esthetic example, has great associations and is simply superb for the specie.

Rosasite on Malachite over Mimetite
stock #17.1-533
Tsumeb
Otjikoto Region, Namibia
5.3 x 4.4 x 3.2 CM (small cabinet/ large miniature)
price: $390
Early summer 2021

A choice example of Rosasite from Tsumeb, this is formed on and next to Malachite which has formed over Mimetite. Several Mimetite crystals have also formed on top of the Rosasite, adding a nice color contrast. The central "tower" of botryoidal Rosasite is about 2.5 CM (inch) tall, with a velvet luster that gives a nice focus to the specimen. Tsumeb is unquestionably the locality that has best mixed many beautiful secondary minerals of diverse elements, habits and forms.

Fluorite - rare
stock #21.1-239
Mahodari, Sinnar, Nasik District
Maharashtra, India
6.2 x 4.4 x 2.8 CM (small cabinet/ large miniature)
price: $160
Early summer 2021

A small but distinct single ball of red Fluorite is nestled in a matrix of Quartz crystals. From earlier finds at Nasik, there have been a lot of ball shaped Fluorite found in recent years, but the red color is very rare, almost never seen for years. There have also been many fakes with dyes used to color the Fluorite. This is a fully natural, real example with the ball just under 1 CM across. Hard to find and when available the prices can be incredibly high. A nice example at a reasonable price, good value for any lover of Fluorite or Indian minerals.

Silver - classic German locale
stock #20.FC-026-(9123)
Freiberg District, Mittlesachsen
Saxony, Germany
4.6 x 3.3 x 1.6 CM (miniature)
price: $2300
Early summer 2021

A complex tangle of Silver wires and ropy masses rises from a pure Silver matrix composed of smaller wires. An old piece from the classic Freiberg district, this is an especially fine example of several wire forms and has a great overall esthetic. A vintage Deyrolles (Paris) label is included, however the specimen age is not known (Freiberg produced Silver since the 12th century, the last mine closed over a half century ago). In fine condition and with a mix of patina, most is a dark silver-black but there are zones of brighter golden luster which gives great contrast.

Fluorapatite with Cookite
stock #15.1-872
Mount Rubellite, Hebron, Oxford County
Maine, United States
5.2 x 3.3 x 2.5 CM (small cabinet/ large miniature)
price: $580
Early summer 2021

A richly crystalized purple Apatite from the classic Mt Rubellite in Maine. The Apatites show the distinctive "Hebron" form and cover the two largest faces and much of the sides on this piece. The crystals are also quite gemmy. This has a boxwork matrix of Cookite etc, and the luster is especially bright. In fine condition and with very good purple color, this can be displayed from almost any angle. Any nice purple Apatite from Maine is usually very hard to find as these are highly sought after, very little is found and only obtained from older collections.
