A portion of a colour-zoned tourmaline crystal exposed in quartz matrix. A bit of termination exposed as well. The specimen has a thin olive green to black outer zone, green/blue inside across prism; black termination. Translucent to transparent, with gemmy areas. Collected by P. Tarasoff, 24 May 1966.
Condition-wise, this is an excellent fluor-elbaite tourmaline. Glassy prism, wonderful blue-green interior, and an excellent termination (though mostly buried in matrix). These specimens are almost always broken in-situ, making this a significant tourmaline specimen for Canada! With great care the crystal could potentially be exposed even more with the right tools.
