The main component of cassiterite is tin oxide, which is an oxide mineral, often containing trace elements such as iron, niobium, tantale, titanium and manganese. Cassiterite is a tetragonal crystal system. The crystals are often short columnar, slender columnar or double cone-shaped, and the conical aggregates are block, granular or kidney-shaped; with diamond luster to […]

Rutile belongs to the tetragonal crystal system, the crystals are columnar, biconical or needle-shaped; they have diamond luster to semi-metallic luster, transparent to […]
Apatite is a calcium phosphate mineral with complex chemical composition, often containing cerium, uranium, thorium and rare earth elements. According to the different additional anions, it is divided into fluorapatite, chloroapatite, hydroxyapatite and There are many varieties of strontium apatite and so on. They have a similar relationship with each other, and fluorapatite is usually […]
Cyanite, dont le nom anglais est Kyanite, est dérivé du grec Kyanos, qui signifie “bleu”. Il a aussi un autre nom anglais, Les baisers, qui vient aussi du grec, qui signifie “double” et “force”. Il fait référence à différentes duretés. Il présente l'une des plus grandes caractéristiques de la cyanite, C’est, the product is in different directions on […]
Iolite, whose English name is Iolite, comes from the Greek word, signification “violet”, indicating the gem-level color characteristics. It also has several English names, one of which is Cordierite, named after the French geologist who first described the mineral in the 19th century, Pierre Louis Dental Die (PLCordier); the second, Dichroite, also from In Greek, […]
Hemimorphite is a silicate mineral with zinc as the main component. Il contient 53.7% zinc and sometimes contains a small amount of aluminum and iron. It is an important mineral of metallic zinc, and only a few colorless and transparent crystals are used as gems. Hemimorphite belongs to the orthorhombic crystal system, and the crystals […]
Pyrite, the English name Pyrite, comes from Greek and means “spark”, because this mineral emits sparks when hit by hard objects such as steel. Because the surface of pyrite is yellow-brown, it has a strong metallic luster on the crystal surface or polished surface, and is often mistaken for gold, donc on l'appelle aussi […]
La staurolite est un minéral silicaté hydraté d'aluminium et de fer.. Il appartient au système cristallin monoclinique ou pseudorhombique. Les cristaux sont bien développés et sont en colonnes courtes.. Ils ont généralement une croix avec un angle de 90° ou un X avec un angle de 60°. Forme à travers le double cristal. The staurolite has […]
L'épidote est une sorte d'aluminosilicate de calcium hydraté avec une structure insulaire. Parce que sa composition contient souvent divers oligo-éléments comme le manganèse, magnésium, chrome, sodium et potassium, il existe de nombreux types de substituts similaires, comme Il est riche en manganèse comme la monédrite, le chrome est contenu dans l'épidote de chrome, and calcium is replaced by […]
La mine de plomb molybdène, le nom anglais Wulfénite, porte le nom du minéralogiste autrichien Franz Wulfen (F.X. Wulfen, 1728-1805). Molybdénite, également appelé couleur molybdène, est un minéral de molybdate de plomb, appartenant au système cristallin tétragonal, et les cristaux sont en forme de plaques tétragonales. Il a un éclat de graisse à un éclat de diamant, transparent à translucide, et […]
