Geological Formation and Sources
January: Garnet
Garnet is a group of silicate minerals that come in various colors, including red, green, orange, purple, yellow, pink, and black. The most common variety is the deep red almandine garnet, which is found in metamorphic and igneous rocks. Garnet forms under high pressure and temperature conditions, typically in regions where the Earth’s crust has undergone significant geological activity.
Garnet is found in numerous locations around the world, including Africa, Asia, Australia, and the Americas. Major sources include Mozambique, Tanzania, Sri Lanka, and the United States. The gemstone is often mined in pegmatites and metamorphic rocks, where it forms in association with other minerals such as quartz, mica, and feldspar.
The diversity of garnet colors is due to the different chemical compositions within the garnet group. For example, green tsavorite is a variety of grossular garnet that contains vanadium, while orange spessartite is rich in manganese. This variation in color and composition allows for a wide range of uses in jewelry and decorative arts.
