Rubellite, the pink/red variety of elbaite, is one of tourmaline’s most sought-after and rare colors, second only to the coveted Paraiba. With the exception of ruby and red spinel, rubellite is the only other gem known to occur in such a rich, dark red color. Like precious ruby, rubellite derives its name from the Latin word rubellus meaning red. Rubellite carries strong love energy and encourages positivity. Tourmaline is the birthstone for October.
