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-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-03/27 - Calcite and sphalerite Gordonsville Mine, near Carthage, Smith Co. (Tennessee, USA) Interesting large composite crystal of golden calcite with transparent edges and showing a multiple termination (about 8 cm. across from tip to tip at the termination). There is a piece of chert attached to the calcite, coated with tiny colorless quartz crystals on which rest a few 2 mm. white rhombs of dolomite and reddish masses and crystals of sphalerite. Other lustrous crystals of spahalerite to about 1 cm. rest directly on the calcite. Bottom (helps to display) and back (seen in the picture on the right in the central raw) are cleaved, however teminations are completely undamaged. 14x11x8.5 - 150 € |

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 € |

| WUSA-02/60 - Galena West Fork Mine, Reynolds Co. (Missouri, USA) Lustrous crystals of galena to 2 cm. on limestone matrix covered by 1 mm. white crystals of dolomite. Galena crystals belong to two generations, first as complex octahedral crystals with small cubic modifications and second represented by a solitary cubic crystal perched on the former. There are a few 1 mm. chalcopyrite crystals and one 4 mm. pyrite cluster. 6x5.5x5 - 30 € |

WUSA-MS/1 - Sphalerite Picher (Oklahoma, USA) Nice black crystal of sphalerite. There is a small piece of chert attached with some dolomite and small crystals of sphalerite and chalcopyrite. Cleaved at back. 3.5x2.4x2 - 10 € |

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 € |

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-01/71 - Fluorite and barite Rosiclare Level, Minerva Mine #1, Cave-in-Rock District, Hardin Co. (Illinois, USA) Nice group of yellow cubic crystals of fluorite to 4.5 cm. on edge with a mosaic texture on some faces and a nice purple rim. Some faces are partially disolved by the preferential dissolution of previous barite, some of which still remains in a few areas. There are a couple of colorless scalenohedral crystals of calcite to 0.4 cm associated to tiny white barite crystals. Bottom is contacted or cleaved, top is undamaged. Mined in 1993. 5.4x5.4x4.5 - 65 € |

WUSA-01/70 - Fluorite and sphalerite Rosiclare Level, Minerva Mine #1, Cave-in-Rock District, Hardin Co. (Illinois, USA) A matrixless cluster of highly lustrous translucent razor-edged cubic crystals of fluorite to 4.2 cm. on edge. Color is amber-yellow with a thin purple band followed by a transparent light blue rim. Some dark brown sphalerite at bottom. Bottom is recrystallized with just a few small cleaved areas. The main crystal presents 2 nicks on opposite edges as seen in the photos, otherwise undamaged. Mined in 1993. 6.3x5.5x4.3 - 50 € |

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 € |
