Yellow Opal has the same generic properties as any other Opal but additional properties associated with its colour. Yellow Opal resonates with the solar plexus chakra and therefore has an uplifting and revitalising effect. It can help to reinforce positive emotions and bring emotional stability. It is great for removing blockages, particularly ones that are self imposed and limit personal growth. It can enhance psychic visions and abilities and physically can be used to treat gallstones, kidney stones and helps the body fight infection. Opal has some excellent properties but please do not use or carry Opal if you are feeling down, pessimistic or negative in any way as this stone can reflect moods and manifest beliefs. Opal will however, beam out positive thoughts if you are feeling cheerful and optimistic.
