Apatite (Fluorapatite) - unusual locality
stock #20.1-760
Dolny Bori, Bory, Zaar nad Sazavou District
Vysocina Region, Czech Republic
4.7 x 3.1 x 2.3 CM (miniature)
price: $160

Blue-green Apatite crystals perched on a Feldspar and Quartz matrix. The Apatites are well-exposed, terminated and have a two tone fluorescence. Ex Bohumil Vrzal collection. From an important but less well-known Pegmatite in the Czech Republic, that has been the source of many interesting minerals. Sadly the zone is now closed and reclaimed. The color on this piece is quite a bit more vivid than others I have seen and the terminations are a little more complex than the typical flat tops.

Scheelite with Quartz - unusual locality
stock #21.1-233
Obri Dul
Hradec Kralove Region, Czech Republic
9 x 6.8 x 5.7 CM (cabinet)
price: $330

Scheelite crystals in a Quartz-lined vug with individuals to 1.3 cm across. A choice specimens from the less well-known Czech locality of Obri Dul. Collected in 1960 from this small Skarn area that is noted more for Fluorites and Wollastonite. These are quite sharp and sizable for the location and well-preserved. Good luster, nice light yellow-orange color and strong fluorescence.

Elbaite (Rubellite) - vintage specimen from unusual locality
stock #20.1-686
Dobro Vada, Zdar nad Sazavou District
Vysocina Region, Czech Republic
1.9 x 1.2 x 1 CM (thumbnail)
price: $750
Pre Tucson

A small cluster of bright pink Tourmalines with good translucency and gem transparent sections. This has sharp edges, well-formed striations and flat terminations in excellent condition. Any such specimens from this locality are very rare and any good ones like this are simply never seen on the market. This is mounted on a 19th century style turned wooden base. Certainly the best specimen I have seen from this locality but honestly I have seen very few others, and none ever outside of museum collections.

Apatite (Fluorapatite)
stock #20.1-759
Dolny Bori, Bory, Zaar nad Sazavou District
Vysocina Region, Czech Republic
5.1 x 3.6 x 2.5 CM (small cabinet/ large miniature)
price: $130
Pre Tucson

Apatite crystals in a Feldspar block from the Phosphate Pegmatite of Dolny Bory (Czech Republic). There are 4 Apatites on the specimen, 3 very tiny but the largest crystal is 7 MM across and 8mm tall. Much of that crystal is embedded in the Feldspar, yet complete and undamaged. The mint green color is unusually vibrant compared to other pieces I have seen. This is from an important Moravian Pegmatite region where all mining has been shut down since the 1970's and mostly reclaimed. We rarely see any specimens from here in the USA.

Berzelianite - rich, rare Selenide
stock #20.1-804
Bukov Mine, Rozna, Zdar nad Sazavou District
Vysocina Region, Czech Republic
7.8 x 7 x 3.1 CM (cabinet)
price: $300
Spring 23

A fine and rich specimen of the rare Copper Selenide Berzelianite. While far from pretty (for many people an ugly specie) this is very large and fine for the specie and shows well the Berzelianite and its alterations to other Copper Selenides. The brown sooty material and the dark metallic versions of the specie are both well-exposed. It seems some associated Tiemannite is present also. There are not very many Selenides in the mineral world, and the deposit at the long closed Bukov Mine (Czech Republic) was perhaps the best known classic source of Copper Selenides. The mineral has a long and rich history being named by James Dana (father of modern mineralogy) for Jakob Berzelius who was the creator of the periodic table, symbols of the Elements and chemical notation, and often called the father of analytic Chemistry. Described in 1850 shortly after the death of Berzelius, in honor of his discovery of the element Selenium and at least 5 other elements. This specimen was collected in 1970 when this could still be found at the site.

Freibergite - Tetrahedrite group on Siderite - classic European
stock #21.1-478
Central Bohemia Region, Czech Republic
7.8 x 4.2 x 3.8 CM (cabinet)
price: $950
Fall 22

A very well-crystallized classic specimen from the ancient mining district of Pribram. The silver-rich Tetrahedrites had been called Freibergite but this is now a discredited specie name but exists as a subgroup tin the Tetrahedrite family. This is a superb piece with well-defined crystals on sizable Siderite crystals. The cluster of Freibergite/Tetrahedrite crystals is 3.2 CM across and is overall in good condition though there are some bruises to mention. despite that this is still a killer for the locality and specie. Silver was chased in this zone going back for centuries, later lead and finally Uranium were sought. Silver species are quite prized and well-crystalized specimens are now rare from this famed mine.

Aragonite - classic, vintage
stock #16.1-499-(CN4680)
Cicov Hill, Horenec, Libceves, Louny District, Usi Nad Labem Region
Bohemia, Czech Republic
5.1 x 1.9 x 1.6 (small cabinet/ large miniature)
price: $420
Fall 22

A classic old Aragonite crystal that does look a lot like a Calcite. It has good yellow to amber color zoning and sharp form that are distinctive to this classic old find. In fine condition and well-terminated, lustrous and translucent. The original labels (see the second photo) do have a mis-identification for the locality showing the coal mining locale of Bilina. Since this find at Cicov hill is world famous, unique and well-documented we can correct this with certainty. The great finds were made at this locale in the 19th century, the George M English label included is from the 1893-1898 era based on the address printed. A true and choice classic specimen Ex Charles M Noll and G. M English

SOLD Fluorite, Quartz and Siderite
stock #SOLD 20.1-864
Krupka, Teplice District
Usti nad Labem Region (Bohemia), Czech Republic
4.1 x 3.1 x 2.7 CM (miniature)
price: $0
new year 2021

A very dark purple cube of Fluorite nestled in a cluster of red and yellow Quartz crystals which are colored by Hematite inclusions. A small bit of Siderite is also noted. An old specimen from this important and very historic Czech locality that has produced many different Fluorites over the centuries. These are not seen for sale very often outside of the Central European region, but they are quite prized there.
