It is usually cut in cabochons, while faceting is avoided because it can cause the gemstone to break. Today Amazonite is located in the Urals in Russia, Colorado and Virginia in the USA, as well as Australia and South Africa.

Amethyst is a variety of quartz that forms fine pyramidal crystals. Its name is of Greek origin. Its hardness is 7 and its specific gravity 2.65. It crystallizes in the orthorhombic crystallographic system and forms crystals in the shape of  hexagonal prisms. It is an impressively beautiful material and meets all specifications to be used for crafting jewelry. However, its price is not very high because it is mined in large quantities. Ancient Greeks believed that amethyst could guard against drunkenness. In the Bible it is identified with the ninth tribe of Issachar and adorns the vestments of the high priest of the temple of Solomon. In the Apocalypse of John, it is the twelfth stone of the new Jerusalem. It is found in sedimentary rocks of Brazil, Uruguay, Mexico, USA, the Urals, the Czech Republic and Switzerland.

A Tektite is a meteorite, which fell from space. It is an amorphous silicate glassy rock which in ancient times was called lightning stone, because people believed that it was due to the lightnings that tektites fell to the Earth.
