Elbaite from
Otjua Mine, Otjua Farm 37, Karibib, Erongo Region, Namibia

Locality type:Mine
Classification
Species:Elbaite
Formula:Na(Li1.5Al1.5)Al6(Si6O18)(BO3)3(OH)3(OH)
Comments:Considered to be the best specimens of pocket tourmaline from Namibian pegmatites. Lots of crystals were badly fractured, commonly seen was green, dark green or blue-black rinds and red to pink cores but said to lack lustre. Large crystals up to 30cm.
Uncertain if these crystals are (at least in part) fluor-elbaite (compare fluor-elbaite entry).

Quality for species:Excellent - world class for species or very significant. (!!)
Confirmation
Validity:Believed Valid
