This one of a kind strand of Paraiba Tourmaline, plain trillions , are from the state of Paraiba, Brazil. They have rare coloring due to their copper content. They are top of the line for rarity in the Tourmaline family. And, hanging in a central position is an intricate vintage face (I love this piece so much) The beads are 5×6-8x7mm and 17″in length.
