TOURMALINE
People have probably used tourmaline as a gem for centuries, but until the development of modern mineralogy, they identified it as some other stone (ruby, sapphire, emerald, and so forth) based on its coloring.
Tourmaline comes in a variety of different colors. In fact, it has one of the widest color range of any gems species.
Birthstone for October and the gem for 8th anniversaries.
