Green and Yellow Tourmaline |
|
|
Yellow-green is the most common of all tourmaline color varieties, but emerald-green is much rarer and more valuable. Indeed, until the 18th century it was often confused with emerald.

|
|
Occurrence |
|
Emerald green stones arc found in Brazil, Tanzania, and Namibia; fibrous yellow material occurs in Sri Lanka.
|
| Remarks |
|
Pale
and colorless beryl was once used for the lenses in spectacles,
thus the German word for spectacles, brills, may have been
derived from the word "beryl".
