Malachite is a powerful stone but one that needs to be handled with caution. It is best used under the supervision of a qualified crystal therapist. It is toxic and should be used only in its polished form.
Malachite amplifies both positive and negative energies. It grounds spiritual energies onto the planet. It is believed by some people that Malachite is still evolving and will be one of the most important healing stones of the new millennium. Malachite is already an important protection stone. It absorbs negative energies and pollutants easily, picking them up from the atmosphere and from the body. It should be cleansed before and after use by placing it on a quartz cluster in the sun (do not use salt, which will damage the surface). Psychologically, Malachite is a stone of transformation. Life is lived more intensely under the influence of the adventurous stone, which encourages risk-taking and change. It mercilessly shows what is blocking your spiritual growth. Malachite draws out deep feelings and psychosomatic causes, breaks unwanted ties and outworn patterns, and teaches how to take responsibility for one's actions, thoughts, and feelings. It releases inhibitions and encourages expressing feeling. The stone develops empathy with other people, showing how it would feel to be in their place. It alleviates shyness and supports friendships.
