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 - Sold MS 1/12 |

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 - Sold MS 11/12 |

(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 - Sold |

(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 - Sold MS 9/12 |
