Please take a look at our new minerals shop!
Here you will find a lot of spare minerals and minerals sets for collection and exhibition also in beautiful display cases. Some curiosities... do you know that when two or more minerals combine together they form a rock? The most common mineral found on Earth is quartz. All minerals are inorganic because they are made of nonliving particles, and all minerals are always solid and have a distinctive geometric shape called crystalline structure.
Now enjoy our collection, new minerals will be added every month!
The mineral Pyrite is also knows as "fool's gold" due to its amazing color, its crystalline structure is well visible, it is made of iron and sulphur, pyrite is the most abundant iron sulfide in the Earth. The name pyrite derives from the the Greek πυρίτης λίθος (pyritēs lithos), it could creat sparks when struck against steel.
The mineral Amazonite it is also known as Amazonstone, it is a green tectosilicate mineral. Its chemical formula is KAlSi3O8, which is polymorphic to orthoclase. Its name is taken from that of the Amazon River, from which green stones were formerly obtained. It has been described as a "beautiful crystallized variety of a bright verdigris-green". Amazonite is also occasionally cut and used as a gemstone in necklaces and bracelets.
Copal is a solidified, rich plant resin, that can be colourless, yellow, brown or rarely reddish. It is a relatively recent fossil resin, which may have only tens or hundreds of years unlike Amber (millions years). Copal is frequently used as an imitation of Amber.
Kauri gum is a variety of Copal from New Zealand. Manila is the Copal from the Philippines and Indonesia. Dammar is a variety of Copal from Malaysia.
The mineral was named Apatite by the German geologist Abraham Gottlob Werner in 1786, although the specific mineral he had described was reclassified as fluorapatite in 1860 by the german mineralogist Karl Friedrich August Rammelsberg. Apatite is often mistaken for other minerals. This tendency is reflected in the mineral's name, which is derived from the Greek word απατείν (apatein), which means to deceive or to be misleading.
Selenite, satin spar, desert rose, gypsum flower are crystal habit varieties of the mineral "gypsum".
All varieties of gypsum, including selenite and alabaster, are composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O.
Selenite contains no selenium, the similarity of the names of the substances coming from the Ancient Greek word for the Moon.
Orpiment is a common orange-yellow arsenic sulfide. It is found in volcanic fumaroles. Orpiment takes its name from the Latin auripigmentum (aurum, "gold" + pigmentum, "pigment") because of its deep-yellow color. Alchemists often used orpiment to try to get gold from copper, of corse it was impossible, because orpiment doesn't not contain any gold.
