In the USA Gallery we present some minerals from districts and localities all over the country from Maine to California. In Page 1 you can browse through nice calcites, old millerites, wulfenites, dioptases, elbaites and others while Page 2 is devoted to specimens from Mississippi Valley-type deposits as the Elmwood-Gordonsville District in Tennessee, the Viburnum Trend in Missouri and the Illinois Fluorspar District.

 

WUSA-03/26 - Calcite and sphalerite

Gordonsville Mine, near Carthage, Smith Co. (Tennessee, USA)

Large heavy lustrous translucent golden twinned calcite crystal with a multiple termination on one end. There are some pieces of chert attached, coated by tiny colorless quartz crystals and 2 mm. white rhombs of dolomite. Numerous lustrous crystals of brown sphalerite to 1.5 cm. across with associated brassy chalcopyrite are also attached to the calcite crystal or the chert. Bottom (helps to display) and back are cleaved, otherwise presents minor bruising in a couple of areas and very little damage at the terminations.

14.7x13.5x8.5 - 220 €

MS 1/12

 

 

WUSA-09/24 - Calcite

Elmwood Mine, near Carthage, Smith Co. (Tennessee, USA)

Nice matrixless doubly terminated transparent golden scalenohedral crystal of calcite with some white barite at back. Presents some contacting near the top termination as seen in the pictures and really minor cleaving at the termination, something otherwise quite common in calcites from this classic American locality. Better than most seen currently in the market.

11.3x6.2x4.5 - 90 €

 

 

WUSA-10/40 - Calcite

Sweetwater Mine, Reynolds Co. (Missouri, USA)

Nice floater cluster of highly lustrous transparent to translucent golden-yellow crystals of calcite to 4 cm. long. Color is more intense than usual for calcites from this locality. Bottom is contacted/recrystallized and presents some small brassy chalcopyrite crystals to 2 mm. across. One minor calcite crystal attached to the main crystal is cleaved at back, otherwise undamaged and quite interesting.

4.7x3.1x2.1 - 35 €

MS 11/12

 

 

WUSA-10/42 - Calcite

Sweetwater Mine, Reynolds Co. (Missouri, USA)

Nice floater cluster of lustrous transparent to translucent yellowish crystals of calcite to about 4.3 cm. long. Bottom is contacted/recrystallized and presents some small golden chalcopyrite crystals to 2 mm. across. One crystal presents a tiny cleavage at the termination, otherwise undamaged and quite interesting.

7.4x5.5x2.3 - 60 €

 

 

WUSA-10/43 - Calcite and galena

Sweetwater Mine, Reynolds Co. (Missouri, USA)

A loose highly lustrous translucent doubly terminated calcite crystal of yellow color. Presents some globular pyrite and small white crystals of dolomite associated as well as some cleavings of galena at back. Great crystal with just minor cleaving at back in the contact with the galena, otherwise undamaged and with both terminations in great shape.

9.3x3.5x2.8 - 65 €

MS 10/12

 

 

WUSA-14/16 - Sphalerite, chalcopyrite and pyrite

Picher Field, Tri-State-District, Ottawa Co. (Oklahoma, USA)

Cluster of red to brown resinous sphalerite crystals with a partial coating of tiny cubic pyrite crystals. There are a few chalcopyrite crystals to 4 mm. across and some marcasite little groups coating the chalcopyrite. Minor cleaving at bottom where it was attached to matrix and a few tiny nicks here and there as only damage. Ex Steve Pullman collection.

4.4x4.2x3.6 - 20 €

 

 

WUSA-MS/3 - Sphalerite

Picher (Oklahoma, USA)

Small cluster of black crystals of sphalerite cleaved at back. Some damage as seen in the picture.

3.5x2.4x1,8 - 10 €

 

 

WUSA-02/33 - Fluorite and sphalerite

Rosiclare Level, Cross-Cut Orebody, Minerva Mine #1, Cave-in-Rock District, Hardin Co. (Illinois, USA)

Mound of lustrous reddish brown sphalerite crystals with two fluorite crystals attached. The largest is a lustrous cloudy yellowish 3.7x3.2x2.3-cm. cube with some faces and back partially disolved by the preferential dissolution of previous barite. Presents a thin purple band followed by a 2-mm. light blue to colorless outer rim. On this outer area and included in it there are numerous tiny brassy chalcopyrite crystals. The smaller fluorite crystal is a lustrous transparent 7x7x6-mm. cube of purple to light blue color. Some cleaved areas in the sphalerite but the fluorites are undamaged. Mined in 1990.

6.5x5x3.5 - 40 €

MS 11/12

 

 

WUSA-02/49 - Fluorite and sphalerite

Rosiclare Level, Annabel Lee Mine, Harris Creek District, Hardin Co. (Illinois, USA)

Very dark to almost black purple cubic crystals of fluorite to 2.1x2.1x1.8 cm on a matrix of lustrous reddish brown sphalerite crystals. The fluorite at top left on the photo at right is translucent when backlit and is recrystallized with one corner cleaved at back. Some damage where one crystal is lacking as can be seen in the bottom right picture, difficult to appreciate when handled, otherwise in very good shape. Mined in 1995.

7.5x6.7x4.3 - 40 €

 

 

WUSA-01/73 - Fluorite and galena

Hill-Ledford Mine, Cave-in-Rock District, Hardin Co. (Illinois, USA)

A matrixless cluster of translucent purple fluorite crystals to 3.3x3.3x2.3 cm. with a nice zoning associated to lustrous metallic cubic galena crystals with octahedral modifications on the corners. Some crystals of galena are tabular as can be seen in the bottom right picture. The large fluorite crystal apparently has a cleaved corner, however it is smoothly recrystallized. Bottom presents some cleavages in the fluorite as well as in the galena. The display face is quite well. Mined in the mid 60's.

7.5x6.5x4.8 - 95 €
