Bornite

Cu5FeS4  -  02.BA.10 (Strunz)
(from La Rafaela Mine, Cabildo, Chile)

Bornite’s party! These specimens of bornite have a fantastic blue color, characteristic of the oxidation of this mineral. These samples come from the best law sector of the site, with about 3%.

Orange Quartz

SiO2  -  4.DA.05 (Strunz)
(from Chile)

This is a fine specimen of quartz orange color. The color of this specimen is because impurities in its crystal structure, is translucent and very tough.

Byssolite

Ca2(Mg4.5-2.5Fe2+0.5-2.5)Si8O22(OH)2  -  09.DE.10 (Strunz)
(from 
Keystone Trap Rock Quarry¸ Cornog¸ Wallace Township¸ Chester County¸ Pennsylvania)

Here we have an interesting and aesthetic specimen of Byssolite (actinolite). This mineral is a variety of Amphibole Supergroup (asbestos). The Byssolite forms as numerous long thin needle-like (almost hair-like) radiating crystals. Has a beautiful green fibrous form. Like all asbestos, is toxic and carcinogenic.

Bismuth

Bi - 01.CA.05(Strunz) 
(from Germany, grown lab)

Here we have some Native bismuth ‘crystals’. They form as a ‘hopper’ type of crystal network. They have a bright metallic luster and show a beautiful iridescent rainbow play of colors. Bismuth is the last element to decay in the universe. The average life of an estimated 20 trillion years. It is equally rare in the crust than gold.

Mottramite

PbCu(VO4)(OH)  -  08.BH.40 (Strunz)
(from 
Mina la Ojuele, Mapimi, Durango, Mexico)

Here we have a specimen of the hydrated lead and copper vanadium oxide mineral mottramite from Mexico. This is a relatively new find from the Mina la Ojuele mine. The mottramite forms as sharply formed mammilary masses that have a yellow to dark greenish-brown color. The mottramite has a ‘matt-like’ to silky luster. The mottramite specimens from this locality represent really excellent specimens from this species. Has a visible Pleochroism.

Emerald

Be3Al2(SiO3)6::Cr  -  9.CJ.05 (Strunz)
(from Bogota, Colombia [rough], from Minas Gerais, Brazil [cut])

Emerald is a variety of the mineral called beryl, it contains chromium and vanadium, which give it its characteristic emerald green color. The big one, is a Colombian Emerald Rough, but is less clear than the other. The little one, is a cut gem (emerald cut to minimize impacts), very beautiful and clear, with a distinctive color of its origin (Brazil).

Gold Chalcopyrite

CuFeS2::Au  -  02.CB.10a (Strunz)
(from El Inglés Mine, Chancón, Rancagua, Chile)

This Chalcopyrite is special because it contains within about 150 ppm Gold (parts per million), I mean a high concentration of this precious metal. Has a brass and gold yellow color. From Chancón near from my native town. I took a photo at the entrance to the “El Inglés mine”, to see as it was.

Fuchsite

K(Al,Cr)2AlSi3O10(OH,F)2  -  9.EC.15 (Strunz)
(from Brasil)

Variety of green muscovite by high chromium content in the crystal structure, the aluminum is replaced by trivalent chromium. Muscovite is the most common mica, found in granitespegmatitesgneisses, and schists, and as a contact metamorphic rockIt is anisotropic and has high birefringenceIt has a highly-perfect basal cleavage yielding remarkably-thin laminæ (sheets) which are often highly elastic.

Mercury

Hg - 01.AD.05 (Strunz)
(obtained through chemical processes)

Mercury (☿ The symbol for the planet Mercury has been used since ancient times to represent the element) the famous liquid metal, is a heavy, silvery-white metal. Was named after the Roman god, this element is 13.5 times heavier than water, so dense than a cube of steel, could float on it. Mercury and most of its compounds are extremely toxic and must be handled with care. I uploaded a Gif for you to see the dynamics of this fascinating element, enjoy it! http://i.minus.com/iULltbavmSGyJ.gif

Sugilite 

KNa2(Fe3+)2(Li3Si12)O30  -  9.CM.05 (Strunz)
(from Kalahari Manganese Fields, Northern Cape, South Africa)

This specimen has a dazzling color purple, I bought this beautiful and rare cyclosilicate mineral from the Kalahari Manganese Fields. It comes out of Nchwanning III mine. To the west of Kuruman in the Northern Cape province, South Africa lies the enormous manganese deposits of the Kalahari manganese field which covers at least 1100 square kilometres. These deposits have become world famous not only for the enormous reserves of ores, but also for a wide range of spectacular specimens. Up to date there are 140 different species of minerals classified from this  locality. It has radioactivity but is barely detectable.
