Varieties

Achroite

farblose Varietät des Elbait

Chromian Elbaite

grüne, Cr(III)-haltige Varietät des Elbait

Indicolite

Indigolith wird blauer Elbait genannt, wobei es sich meist um ein relativ dunkles Blau, oft mit einem Stich ins Grüne, handelt. Blaue Turmaline sind sehr viel seltener als grüne oder rosafarbene.

Paraibaite

Paraibait ist eine blaue kupferhaltige Varietät des Elbait-Turmalins.

Rubellite

Rubellit ist ein rosa bis rot gefärbter Elbait, der in Hohlräumen und Drusen von Pegmatiten auftritt (Edelstein-Varietät)

Tsilaisite (Elbaite)

Tsilaisit = Mn-haltiger Elbait

Verdelite

Verdelith ist ein grün gefärbter Elbait (Edelstein-Varietät)
