Calcite with Chalcopyrite - USA Classic
stock #21.1-069
Bethel Level, Annabel Lee Mine, Ozark-Mahoning Co.
Illinois, United States
6.7 x 6.7 4.3 CM (cabinet)
price: $80

Calcite crystals in modified rhombs from the Fluorospar region of Illinois. These are dusted with sparkling crystals of Chalcopyrite and have an epitaxial alignment. In very good condition, most of the crystals are perfect and damage-free. The specimen has a small break on the underside where it was removed and some tiny rough spots (.5 mm) are seen with a loupe. An old label from Ross Lillie (North Star Minerals) is with this piece.

stock #20.1-279
Santa Rosa Mine, Itambacuri
Minas Gerais, Brazil
2.6 x 1.3 x 1.3 CM (thumbnail)
price: $80
new year 2021

A zoned green flat top terminated Elbaite crystal from old finds at Santa Rosa. The crystal has good glassy luster, moderate transparency and only one small .5 mm chip. Weighs 7.4 Grams, this is priced below typical market rates. Pretty, affordable tourmaline that glows well when backlit.

stock #0888-JM-3125
Miners Ridge, Red Mountain, Mendocino County
California, United States
7.2 x 4.9 x 3.3 CM (cabinet)
price: $90
new year 2021

A good sized blocky matrix with Mcguinnessite in rich crystalline crusts on several faces. Ex John Marshall collection, this is from the type locality area of Red Mountain. Close exam shows there are many tiny spheres and cups of blue green mineral, as well as some massive zones. A nice example of this unusual Copper mineral.

Tangeite (Calcio-Volborthite)
stock #21.1-044
Kayenta, Navajo County
Arizona, United States
2.8 x 2.2 x 1.4 CM (thumbnail)
price: $90
new year 2021

Colorful thumbnail of this uncommon Copper-Vanadium specie from Arizona. This specie was known as Calcio-Volborthite for many years but is now renamed Tangeite after this was re-described from an older type locale in Kyrgyzstan. Well-formed crystals on contrasting matrix that are especially vivid under the microscope. This mining area close to Monument Valley has several small old workings which were sources as far back as the late 19th century.

stock #15.1-032
Elmwood Mine, Carthage
Tennessee, United States
4.7 x 3.9 x 2.9 CM (miniature)
price: $90
new year 2021

A dark purple to purple blue Fluorite from the Elmwood Mine that has some zoning and is fairly transparent. A nice colorful Fluorite that glows well when backlit. So much USA Fluorite has become very expensive, this is an affordable specimen in very good condition from this classic USA locale.

Bustamite, Calcite, Sphalerite, Chalcopyrite etc.
stock #13.1-283
Broken Hill, Yancowinna County
New South Wales, Australia
2.1 x 1.8 x 1.3 CM (thumbnail)
price: $90
new year 2021

A cute thumbnail with the focus being one larger crystal of Bustamite. The specimen also includes some very tiny Spessartine as well as the Sulphides listed above. The Bustamite has the typical crude or melted look on some edges but is distinctly terminated and well-defined. Broken Hill is a famed locality that is on every short list of world class deposits and is certainly a classic.

Beryl var. Aquamarine
stock #20.1-341
Governador Valadares, Doce Valley
Minas Gerais, Brazil
2.7 x 2.2 x 1.5 CM (thumbnail)
price: $90
new year 2021

A clean and very lustrous gem crystal with a well-defined form. An older Brazilian piece with an unusual habit that is quite different from the typical elongated hexagon. Not super perfect under close inspection as there are some tiny edge nicks, but this still looks fine and has nice color, transparency and crystal form.

Faujasite with Augite in Limbergite matrix
stock #20.1-916
Sasbach, Kaiserstuhl, Baden
Baden-Wurttemberg, Germany
5.3 x 4.2 x 3.8 CM (cabinet)
price: $50
new year 2021

An old specimen of this rather scarce Zeolite specie from the most prolific locality at Sasbach, Germany. Many small cavities on all sides hold white linings of tiny Faujasite crystals and botryoidal masses. The crystals are typically very tiny octahedra best seen with good magnification. Some small Augite crystals are also present. This is not an "esthetic" specie with crystals typically under 1 mm, but this is a good example none the less. Ex. R and A Palmer collection from the Joe Mandarino study suite.
