Tourmaline most commonly occurs as an accessory mineral in igneous and metamorphic rocks. Large, well-formed crystals of tourmaline can form in cavities and fractures during hydrothermal activity. Tourmaline is a hard and tenacious mineral. That enables it to persist during stream and beach transport as durable grains in sediments and sedimentary rocks.
Tourmaline is one of the world's most popular gemstones and it serves as a birthstone for the month of October. Because of its popularity, tourmaline is easy to find in jewellery stores. Well-formed tourmaline crystals are also valued by mineral specimen collectors. Specimens with attractive colours and crystal forms can sell for thousands of dollars.
The wide range of compositions and colour zoning within crystals causes tourmaline to occur in more colours and colour combinations than any other mineral group.
