Hello there lovely!
Opal Aura Quartz - Clear Quartz bonded with Platinum; creates a pearly sheen with pale rainbow iridescence. Opal Aura has a very intense, strong energy that cleanses the aura, and stimulates, balances and clears all chakras, integrating the light body into the physical dimension.
It is a crystal of joy, and like a rainbow, signifies hope and optimism.
