Manganotantalite (Twinned)
Small Cabinet, 7.0 x 4.5 x 4.3 cm
Lavra de Cori, Bahia, Brazil
An outstanding, dramatic twinned crystal of this rare earth species, showing great luster AND form...rare in such a crystal. Also, most tantalites from Brazil are flat-topped and just plain brutish looking. This is as elegant as I can imagine a tantalite crystal to be! Note it is nearly pristine with just a few trivial dings, and otherwise it is complete all around. In some lighting, it acquires a surface iridescence, you can see. This is exceptional not only for Brazilian examples of this species, but for ANY locale
