- Alto do Giz pegmatite, Equador, Borborema mineral province, Rio Grande do Norte, Northeast Region, Brazil
- Miniature, 3.2 x 2.1 x 1.3 cm
A sharp, terminated crystal of Tantalite from Brazil. This 3.2 cm-wide crystal is exceptional for its size, and the lustrous striated faces are very attractive. The main termination is nearly complete, and very sharply carved with only a few minor bits of edge wear. Overall, an excellent and aesthetic Tantalite. Ex. Charlie Key.
