These stones can cause serious damage to health, even just beautifully being on the shelf as an interior decoration or a sample from the collection.
So, from the least dangerous to the most dangerous.
10. Chalcanthite (Chalcanthite) – other Greek. – copper and other Greek – flower. Seductive blue chalcanthite crystals are composed of copper, combined with sulfur and other elements, as well as with water. Such a composition turns copper, which is necessary for the body, but which becomes toxic in excess, into a very bioavailable crystal. In other words, copper becomes soluble in water, and can be absorbed in large quantities by any plant or animal, quickly weakening it, and then killing it because important internal organs stop working.
Amateur scientists should never try chalcanthite for salt content, because in this case they can have an extremely serious overdose of copper. Simple extraction of a crystal of this blue mineral killed all the algae in the whole pond, in addition, these crystals can create great environmental problems. Due to the incredible beauty and rarity of chalcanthite, an enterprise has grown in the geological community to grow artificial crystals for sale, which are advertised as genuine samples.
9. Coloradoite (Coloradoite) – named after pcs. Colorado, USAColoradoite is a recently discovered crystalline mineral commonly found in magma veins. This mineral is a mercury telluride compound formed by the alloying of mercury with tellurium, another extremely toxic and rare metal. Therefore, coloradoitis is a double toxic threat to those who dare to pick it up. The combination of these two elements creates the risk of serious poisoning due to careless handling. When heated or chemically altered, this strange mineral releases deadly vapor and dust.
What is most interesting – this mineral is mined to obtain tellurium contained in it. Tellurium minerals can also be found in combination with gold, however, such combinations were not previously known. By a strange will of fate, coloradoite deposits were developed in Australia during an unusual gold rush after people realized that potholes in the roads were filled with tellurium stones containing gold.
8. Hutchinsonite (Hutchinsonite) – named after Hutchinson. Tallium is a gloomy twin of lead. This dense, fatty metal is like lead in atomic mass, but is even more deadly. Thallium is a rare metal that appears in very toxic compounds consisting of rather strange combinations of elements. The effects of thallium are even stranger, and include hair loss, serious skin contact and, in many cases, death.
Gutchinsonite is a dangerous but striking mixture of thallium, lead and arsenic. Three toxic metals form a lethal cocktail of minerals that must be handled with great care. Gutchinsonite was named after John Hutchinson, a well-known mineralogist from the University of Cambridge. This mineral can be found in the mountainous regions of Europe, most often in ore deposits.
7. Galena (Galena) – (from lat. Galena – lead ore) Galena is the main ore used for mining lead. It is a shiny silver cubes unnaturally perfect shape. Despite the fact that lead is generally very flexible, the sulfur content in galena makes it extremely fragile and malleable for chemical treatment. Galenite can cause serious consequences for workers and amateur researchers who worked with it without observing safety measures.
Sample handling may result in inhalation of dust. Workers in mines are at high risk of poisoning from contact with minerals and deadly dust generated during production. After mining, lead from this mineral poses an environmental threat to human health during its processing and purification. Galena has a cubic fracture process, and if you hit it with a hammer, the crystal will break into several smaller copies of its original shape.
6. Asbestos (Asbestos) – (Greek, – indestructible)
Chrysotile (Chrysotile) and Amphibolite (Amphibolite)
Asbestos is not an artificial product, however, it is one of the most terrible minerals on the planet. While other minerals act as toxins due to their chemical composition and accidentally poison victims, asbestos is carrying out mechanical sabotage to the lungs of a person to the fullest. Asbestos belongs to the completely natural category of minerals and consists of silicon dioxide – the most abundant solid mineral on Earth, iron, sodium and oxygen.
