This mineral was first discovered in Saxton, Germany in 1832 by François Sulpice Beaudant. He chose to name it after the Greek word “Erythros”, meaning “red”, which was the color of the first specimen he discovered.
Where is Erythrite found?
The largest and some of the most vivid Erythrite crystals come from the Bou Azer district in Morrocco. This part of Morocco has produced gorgeous, 'masterpiece' specimen. Notable mines here include the Aghbar Mine and the Agoudal Mine. Erythrite has also been found at Mount Cobalt in Queensland, Australia.
What type of rock is Erythrite?
Erythrite occurs as a secondary mineral, forming from the oxidation of other minerals in sedimentary and metamorphic rocks. Erythrite is usually associated with quartz, calcite, limonite, and the ores of more col- lectible minerals such as cobaltite, skutterudite, scoro- dite, pharmacosiderite, adamite, and malachite.
Where is Spherocobaltite found?
The Optical properties are Uniaxial (–) with 1.885 – 1.600 Refractive Index. The Birefringence value of the stone is 0.285 and also its Specific gravity is 4.10 – 4.13 (g/cm3). It is usually found in shades of pink from pale pink to rose red, to deep pinkish red. Current sources are Morocco, Spain, and Congo (Zaire).
What mineral group is Erythrite in?
Erythrite, also called Cobalt Bloom, arsenate mineral in the vivianite group, hydrated cobalt arsenate [Co3(AsO4)2·8H2O].

What type of rock is Skutterudite?
Minerals and rocks
Skutterudite is a cobalt arsenide (CoAs3), and cobalt-nickel arsenide (CoNiAs3-x) mineral with variable amounts of nickel and iron. It is named after the city of “Skotterud,” Norway. The mineral occurs as distinct cubes with octahedral crystal system.
How is Cobaltite formed?
It occurs in high-temperature hydrothermal deposits and contact metamorphic rocks. It occurs in association with magnetite, sphalerite, chalcopyrite, skutterudite, allanite, zoisite, scapolite, titanite, and calcite along with numerous other Co–Ni sulfides and arsenides. It was described as early as 1832.
What are carbonate minerals used for?
Other relatively common carbonate minerals serve as metal ores: siderite, for iron; rhodochrosite, for manganese; strontianite, for strontium; smithsonite, for zinc; witherite, for barium; and cerussite, for lead.
What is Cobalto Calcite?
Cobalto Calcite, also known as Aphrodite Stone, is an uncommon variety of Calcite that has Cobalt impurities. ... Cobalto Calcite will allow the integration of positive energy within all levels of your Chakra system – the positive energy being love, compassion, and the understanding of unity within diversity.
What is calcite mineral used for?
Calcite is the mineral component of limestone which is used primarily as construction aggregates, and in production of lime and cement.
How is wulfenite formed?
Wulfenite is a secondary lead (Pb) mineral, which means it is formed during the oxidation (weathering) of galena, the primary lead mineral. Because wulfenite contains lead, it's pretty heavy for having such thin and delicate crystals! Those crystals are tetragonal and usually found as tabular, flat, square plates.
Why is cobalt red?
The red colour of an aqueous solution of cobalt chloride is attributed to the ion [Co(H2O)6] and the blue colour with the same substance in presence of concentrated hydrochloric acid to the ion [CoCl4]".
How is epidote formed?
It forms when basalts in sheeted dikes and ophiolites are transformed by hydrothermal activity or metasomatism. Unakite is a rock that forms from the metamorphism of granite. Less-resistant minerals in the granite are altered to epidote or replaced by epidote, with the orthoclase and quartz remaining.
Is there a cobalt red?
A reddish secondary cobalt mineral, CO3(AsO4)2·8H2O, found in veins bearing cobalt and arsenic and used in coloring glass.
Where is pink Cobalto calcite found?
This mineral was first discovered in the Calamita mine in Tuscany, Italy. Since then, only a handful of localities have been found throughout the world. The most important veins of this mineral are currently located in the Congo, Morocco, Australia, Mexico, the UK, Spain, Italy, and Switzerland.
What is pink opal?
Pink Opal is a natural, pink colored gem-variety of the Common Opal which is composed of Opal, Palygorskite and Chalcedony. This slightly translucent to opaque gemstone is valued for its unique pink hue, pleasing lustre and high durability rather than the play of color.
What is pink rhodonite?
Rhodonite is manganese silicate mineral with an opaque transparency. Rhodonite comes in shades that vary from pale pink to deep red. It has a vitreous luster and is composed of other minerals such as calcite, iron, and magnesium. ... Rhodonite means compassion and love.
Why is calcium carbonate bad for you?
Calcium supplements may increase the incidence of constipation, severe diarrhea, and abdominal pain. It highlights that calcium carbonate is more often associated with gastrointestinal side effects, including constipation, flatulence, and bloating.
Is calcium carbonate the same as marble dust?
Calcium Carbonate is the generic name for a variety of different minerals found all over the world. For artists and craftspeople there are two types of the material: Chalk and Marble Dust. ...

Is calcium carbonate the same as baking soda?
The sodium bicarbonate version is widely available as "baking soda" and is commonly used in baking, but none of the recipes in this book use it as an ingredient.

What is pyrite made out of?
Pyrite is composed of iron and sulfur; however, the mineral does not serve as an important source of either of these elements. Iron is typically obtained from oxide ores such as hematite and magnetite.
Does scheelite glow?
Scheelite's intense fluorescence under SW UV light and X-rays can help distinguish it from other stones of similar appearance. Although they typically glow an intense bluish white or whitish blue, scheelites that contain some Mo can fluoresce a creamy yellow in SW.
