Azurite is also known as chesilite or blue malachite. It is a copper ore, it is formed in copper deposits that are open pit. It is formed in 69.2% copper, 25.6% carbon dioxide and 5.2% water. Being a copper mineral, azurite is toxic, although it can be in contact with the skin without problems. In the past, azurite was ground to obtain a blue powder as a pigment.

Phantom quartz are also a type of master quartz. Some points of rock crystal quartz crystallize in a particular way, in the previous entry we showed the twin quartz (two almost parallel points sharing the same base). Well, this time we introduce the master quartz phantom quartz. Phantom quartz are those in which a point is first formed and then another point is formed by trapping the first inside. The example in the photo is a green phantom quartz, that is, a large quartz ponit has trapped inside, to an anterior point that had chlorite inclusions.

Twin quartz are included in the family of master quartz. Of all types of rock crystal quartz points, some stand out for presenting peculiar formations. Twin quartz are rock crystal quartz points that have grown almost parallel and together, sharing the same base. In the case of the image, quartz contains inclusions of other minerals, such as chlorite, lodolite and even hematite.

Lepidolite is a mineral that belongs to the group of micas. The first formal description dates from 1792 by Martin Heinrich Klaproth (1743-1817), the name comes from the Greek "lepivβ-lepis" which means shell, because of its scale-forming structure. The lepidolite can be confused with muscovite, the way to differentiate them is by a flame test, the lepidolite results in a crimson flame. The lepidolite can be presented in a variety of colors such as violet, gray or yellow.

Golden obsidian is a variety of obsidian that produces a golden reflex. Obsidian is certainly not a mineral, if not a volcanic rock, it can be classified as a mineraloid (similar to a mineral). The reason is that it is a glass not a crystal (its atoms do not form an ordered structure), in addition to having a composition that is too variable. In this case this type of obsidian has golden reflections for having caught gas bubbles during cooling.

Amethyst is a violet variety of quartz. The violet color is because it contains iron. The intensity of the violet color of the amethyst depends on the amount of iron it contains, the more iron in the amethyst more violet. In the store we have polyhedra made with different minerals such as those of amethyst. Polyhedra are used as a decorative element, or for grills in the esoteric field.

The Rhodochrosite is a little abundant mineral. It is a manganese carbonate. It is considered the national stone of Argentina. It is considered as the reference date of its formal description in 1813. Depending on its impurities, the color may vary from a pure pink to brown. Apart from Argentina, it is also found in Germany, Canada, USA, England, Mexico among others.

" Merlinita "; The name comes from the magician "Merlin" for being considered a magic stone. Its composition is a mixture of quartz and psilomethane (manganese oxide) that forms black layers, specks, or spots within the main structure of the quartz.

Fossilized shark tooth, fossilization is the process by which the soft parts of an organism disappear, while by chemical processes, some harder organic compounds are replaced by minerals.

Pyrite is composed of 53.5% sulfur and 46.5% iron. Its name derives from the Greek root "pyr" (fire) since when it is rubbed with other metals it makes sparks. Pyrite is also known as "the gold of fools" or "the gold of the poor" for its golden resemblance to precious metal. In the photo an example of pyrite sun, with a radial formation, is sometimes confused with some fossil species but it is not.

Amethyst flower, stalactitat of cut and polished amethyst or nodule cut of amethyst. Amethyst is a violet variety of quartz. It was known by the Egyptians, Etruscans and Romans. It was already described by Pliny the Elder (23 or 24 AD - 79 AD). The name in Greek means "against drunkenness"; it was believed that wine drunk from a glass made of amethyst did not lead to drunkenness.

Moldavite is a rock that has been affected by the impact of a meteorite that probably affected southern Germany 15 million years ago, is a type of tectite. It is a glass that contains very little water and is not very hard. Currently, 99% of moldavite comes from southern Bohemia (Czech Republic).
