The name "opal" comes from the Sanskrit word "upala" - precious stone. 
Opal  contains 10% water and the internal structure is made of tiny microscopic beads that create the special opalescent shine because they refract light rays differently. Opal reflects water games and is afraid of heat and drought. In heat and dryness, opal quickly loses its shine as the water dries up. In that case, when you put it in water, after a while the stone seems to come to life and becomes beautiful and shiny again. Opal is fragile. It is not recommended to store in direct sunlight.
