A crystal section of fluor-elbaite tourmaline displaying a mix of greens and blue, in a bed of lithium mica and feldspar. This specimen comes from one of the only places in Canada to produce such crystals, the Leduc Mine of Quebec, Canada, forming within a lithium-enriched granitic pegmatite. The specimens are very hard to break out of the quartz host-matrix and so they generally don't have terminations and often come out in split sections. Perhaps this is for the best as the exterior coating of the crystal is a very dark green, almost black, by having the crystals split like this it allows us to see the colourful and glassy interior of the precious stone.
Collected by Peter Tarasoff in 1966.
