The earrings comes with metal butterfly back, Nice gift. Opal is said to stimulate and amplify the emotional body allowing one to identify and shift the overall pattern. Once the overall energy pattern has shifted the opal vibrates a feeling of joy. This stone is said to have the quality of "holy fire" - an intensity that consumes the impure aspects in our energy without causing us distress or discomfort. If we are willing to let go of our patterns, Opal can be of great help making us aware of what needs to shift, aiding us in making that shift, and finally filling whatever spaces have been created with a joyous feeling.
