Identity HelpElbaite
2nd Sep 2013 21:34 UTCA. A. Faller
I want to post this photo to my gallery, but am a bit uncomfortable now with both the labeled variety of tourmaline it was sold as, as well as the incomplete locality info. The label read: ELBAITE (with muscovite), TAQUARAL, MINAS GERAIS, BRAZIL. The entire crystal is pinkish-red; no green. I acquired it at a show here in the States about 25 years ago. Photos were taken in daylight (not direct sun).
This crystal measures 47.1 mm x 29.1 x 23 mm.
Any of the Brazilian experts able to assist?

I would label it tourmaline with albite var. clevelandite, although elbaite would be OK as well. Elbaite can be green, a lot of the gem tourmaline from Elba is green, for example. Calling it plain old tourmaline eliminates all the varietal confusion.
Very nice specimen by the way!

So Jim is right on this one. Call it tourmaline and you won't be wrong.

Sincerest thanks. Info like that provides me with a perspective I wouldn't otherwise possess...
