Lava is the molten substance released by volcanoes and is an Italian word meaning ‘flooding’. The Earth’s crust is largely made up of solidified lava. Lava is often used to make jewelry. In fact, lava and gagate jewelry were also fashionable in the 19th century during the so-called Victorian period.
Tiger’s eye is one of the most popular quartz varieties. It has a brown color with golden-yellow veins and displays an excellent luster. These veins retain the fibrous structure of crocidolite. It exhibits a characteristic linear iridescence like a moving reflection. This very characteristic optical effect is known by the French word chatoyancy, which means “cat’s eye” and symbolizes the union of the Earth with the Sun. Tiger’s eye is considered to promote decision-making and self-confidence. It is encountered in the USA, South Africa, Namibia, and Brazil.
