A mineral oddity and a choice example of this rare form. Pyrite has formed over a former Marcasite stalactite and is an elongated, slender cube. The central canal hole is visible at the base and the whole piece is complete and terminated. Previously labeled as from Joplin, Misouri, this is quite certainly from the well-known Buick Mine in Iron County some distance away. The cross section of the piece is square and the whole thing is based on an elongated cube form. In excellent condition there is a little overgrowth of later Marcasite on the outside. The luster and color are also good, a bright metallic golden with some silvery spots.
Sphalerite - USA tristate classic
Pelican Mine, Joplin Field, Jasper County
5.6 x 4.3 x 3.2 CM (cabinet)
new year 2021
Textbook perfect, sharp Sphalerite crystal perched on Dolomite with a small bit of Chalcopyrite. The main Sphalerite crystal is complete all around, perfectly undamaged and has the silky luster that is typical from this locale. Through the 1960's, Tri-state specimens were very common even as the mines closed. These are no longer common and are unlike any other Sphalerites from other locales.
Galena - spinel twins, USA
Fletcher Mine, Big Bear orebody, Vibernum Trend, Reynolds County
6.1 x 4.4 x 3.8 CM (cabinet)
new year 2021
A flat habit spinel twinned Galena perched on Dolomite, Chalcopyrite etc. From the Fletcher Mine (Missouri, USA) the Galena is perfect, undamaged and huge for the mine at over 4 CM across. it is very unusual to see from the USA, there have been a few US finds of these over the past decade but never many. The Fletcher Mine is perhaps the most important locality for these twins and this specimen is top notch for the locale based on crystal size and esthetics. In person there is a slight iridescent patina and a slight golden hue mixed with a gunmetal silver.
Calcite on Galena and Chalcopyrite
Sweetwater Mine, Reynolds County
5.1 x 4.8 x 3.7 CM (small cabinet/ large miniature)
A flawless, gem clear Calcite crystal sits well-exposed on a crystallized Galena and Chalcopyrite matrix. From the Sweetwater Mine (Missouri, USA) Ex. Larry White collection, the Calcite is clear enough that the matrix is seen through the crystal. Sweetwater Mine is famed for its Calcites which often have slightly curved faces. This specimen has some but most faces are perfectly flat and have glassy luster. Best appreciated in person, a fine miniature and great value.
Sphalerite on Dolomite -Classic USA
Pelican Mine, Picher, Tri-State District, Ottawa County
6.6 x 5.2 x 4.8 CM (cabinet)
An old Tri-state USA Sphalerite with complex twinned crystals in an intricate cluster. No damage at all, the Sphalerites are complete on all sides (which is rare) and have many distinct penetration notches and ridges. Super presentation and esthetics ex. John Buckley collection, this is far from being a "black ugly" the form is incredible.
Siegenite on Galena
West Fork Mine, Reynolds County
4.3 x 3.7 x 4.4 CM (miniature)
Rich growth of Siegenite crystals on Galena which is in cubes, modified cubes and octahedrons. Quite esthetic for this rare mineral (Cobalt Nickel Sulfide). Ex collections of Steven Chamberlain obtained from the Lendall Hill collection. Fine contrast and with many excellent display angles.
Sphalerite - classic USA
Joplin Field, Tri State District, Jasper County
11.3 x 9 x 4.8 CM (cabinet)
Large, esthetic and in perfect condition, this is an exemplary old Tri-state Sphalerite, mined before 1940. The Joplin field was at one time a seemingly endless source of mineral specimens, though really fine, undamaged pieces were very rare. The last of these mines have all been closed for more than 50 years, and the best specimens came out long before then. This is a superb Sphalerite with large distinct crystals that stand out from the matrix. Crystal faces show complex striations, etchings and some twinning, these have a choice silky luster that shows these structures well. This is incredible in person and very much a superb piece from this now legendary area.
Galena with Chalcopyrite and Dolomite
Brushy Creek Mine, Greely, Viburnum Trend District, Reynolds County
5.9 x 4.6 x 4 CM (cabinet)
Worldwide mix summer
Bright silver color Galena in elongated cube form sits on a finger of matrix covered with small Dolomite and Chalcopyrite crystals. This is the sort of Galena that has made the Brushy Creek locality famous, with extra bright luster, attractive form and in fine undamaged condition. Any suite of lead minerals will have at least one good specimen. These are contemporary classics, still very affordable and unlike the look of Galena from any other area in the world.
