Arubans take myths and superstitions very seriously. They flinch if a black butterfly flits into their home, because this symbolizes death. And on New Year's Eve they toss the first sips of whiskey, rum, or champagne from the first bottle that's opened in the New Year out the door of their house to show respect to those who have died and to wish luck on others. It's no surprise, then, that good-luck charms are part of Aruba's casino culture as well.
The island's most common good-luck charm is the djucu (pronounced joo-koo), a brown-and-black stone that comes from the sea and becomes hot when rubbed. It’s often called the "lucky nut." Many people have them put in gold settings—with their initials engraved in the metal—and wear them around their necks on a chain with other charms such as an anchor or a cross. Another item that's thought to bring good luck is a small bag of sand. The older generation of women might wear them tucked discreetly into their bras.
