Aquamarine With Negative Tourmaline from Pakistan. 1 Piece. Large aquamarine crystal with etch figures at both ends. The hydrofluoric acid causing these figures also etched an included, large tourmaline crystal out of the aquamarine. The result is a surface-reaching "negative crystal", a cavity in the shape of the tourmaline crystal which even shows the tourmalines typical striations!
