The opal is said to recreate the heart, prevent contagion in the air, and dispel sadness; it is also good for weak eyes. Pliny’s description of this stone glows with enthusiasm, and he gives the preference to those that are shadowed as it were with the color of wine. The name pedores, applied to the opal, is recognized to indicate the beautiful complexion of youth. Opal also gives protection and harmony. (see Gem Healing) A.G.H.
