This 11 cm Elbaite is the most significant Tourmaline I have seen from the Leduc Mine in Canada. Collected in 1916 and unrepaired, this single crystal is complete all around (there are sporadic small contacts). The luster is moderate to good, the color uniformly black, and it has a sharp, well-formed termination. Definitely, it is one of the best crystals recovered from this highly erratic and unusual lithium-enriched granitic pegmatite, in the famous Grenville district. Hard to believe! But, she got it from Canadian specialist David Joyce in 1988, directly. A major Canadian piece!
