Green Opal is seen to assist in strengthening all types of relationships; romantic, friends, family and business, especially when worn in a pendant around the neck, (or tucked into your bra next to your heart). It is sometimes referred to as the stone of change. It is a spiritual stone that also assists in opening up psychically. On a physical level, Opal can help to cool a fever and infections and improve memory function. Opal is thought to assist in releasing fear and sending comforting support to those who are grieving. It is a lovely gentle supporting stone.
