Semi rough black tourmaline tip

Veined black tourmaline tip in a semi rough state.

A nice piece of black tourmaline with a polished base and tip keeping the sides in a raw state.

She hails from the mines of Ceará, in Brazil. This variety of black tourmaline has an odd veining with a cracked appearance because its formation is associated with other minerals such as red hematite and white quartz. Its polished part exhibits a nice appearance as if it had been scratched.

It is a unique piece, its weight is about 1,440 kg and its approximate size is 10 cm x 15 cm x 10 cm.
