English: Tourmaline (Var.: Indicolite)
Locality: Pederneira claim, São José da Safira, Doce valley, Minas Gerais, Southeast Region, Brazil (Locality at mindat.org)
Size: 17.3 x 5.6 x 1.4 cm.
This compound cluster of indicolite gem crystals is an unlikely survivor, from a mine and pocket in which nearly all tourmalines were found in pieces. The two crystals, 13 and 7.5 cm in length respectively, intersect dramatically to form a gun-shaped cluster. The 13 cm crystal is terminated at its top (left) end, but has a partially healed, perhaps in situ break at the right end where it sticks out past the junction (and it is possible this termination was "roughed up" a little bit after being found, by rubbing it to dull down an old break - hard to say). The 7.5 cm crystal stands straight up as I would prefer to display this piece (so overall a tan angle), and is terminated on the bottom tip, though the small part sticking up past the junction is broken off. Nevertheless, the major terminations are OK and in the overall geometry, the tiny junction termination and the secondary termination to the main crystal are both secondary to the overall form and the fact that, as a whole, this is unrepaired.
