In ancient Greece they believed Opals gave foresight and prophecy, and Romans used it as a token of purity and hope.
Opals promote a sense of calm and security, allowing the wearer to de-stress, encouraging you to stop brooding and to better direct your thoughts. A karmic stone that teaches you what you put out in the world returns to you. It helps you to release anger and find self worth; bringing loyalty, faithfulness and spontaneity to its wearer.
Opals are the most well known birthstone for October, and is one of the gifts for 12th and 14th anniversary.
