A gem made from hardened teardrops of a mermaid.  A mermaid began appearing at the shipwreck site and ceaselessly cried looking at the remains of the ship.  It is said that she looked so mysterious and yet so sad that no one could dare approach her.  Some claim that this is Ceila, who turned into a mermaid in search of Alberto.  When she couldnt find her lover, they say, she came all the way out here.
