Rutilated quartz, is a type of quartz with needlelike rutile (a titanium dioxide mineral), embedded in it. The rutile needles can be reddish, which is what rutile means in Latin, or they may be golden, silvery, or on very rare occasions, greenish.
Rutilated quartz is reputed to be an energizing stone that helps get energy moving on all levels. It is also said to attract love and stabilize relationships. Rutilated quartz is said to be particularly effective for getting things moving energetically.
Emotionally, rutilated quartz is reputed to diminish fears and to be excellent at assisting with decisions. It is said that it can also ease loneliness and relieve guilt thereby bringing happiness. It is used metaphysically to help one get out of a rut with their life as well as for stabilizing emotional and mental processes, clarifying thought patterns and emotional reactions. Rutilated quartz is also said to increase one's self-reliance and ability to find one's own way.
