I collected this specimen myself by the mine in Socotò in September 2010. The black cristals are Tourmaline, but not Schorl, because they aren transparent yellowbrown in strong light. I think this are Dravite cristals.

"... because they aren transparent yellowbrown in strong light. I think this are Dravite cristals. "


See various previous postings on the identification of tourmaline and schorl.
