Precious opals have two basic colors, their background color and their play of color. The background color is caused by impurities within the silica. Within the precious opal family, there are many different varieties of opal. Each has their own unique color combinations and character traits. Opals can be found orange, yellow, red, green, blue, or purple. Black opals are considered one of the rarest gemstones, though they too can be a variety of dark colors.
Opal's fire carries a spiritual energy that burns through attachments, wounds, and negative patterns. It can amplify your emotions, bringing semi-conscious patterns to the surface of your awareness to be dealt with. When these are cleared, it also amplifies joy.
