Not long after setting sail, Albertos ship encountered a pirate ship.  Once he barely escaped their pursuit hiding in a rocky region, he later struck them back successfully by laying ambush.  With it, all the booty of the pirates came into the possession of Alberto and his men.  The loot most cherished by Alberto was this cobalt emerald.  Alberto is said to have missed Ceila greatly, looking at the emerald which represents youthful innocence.  With this, he planned to ask her hand in marriage upon his return - except that he did not return.
