Both Opal and Tourmaline are the birthstones for the month of October. Tourmalines are well-known in metaphysical circles as wonderful crystals for healing and protection. They are excellent for balancing the hemispheres of the brain, clearing away blockages and transmitting negative energies. Opal is a stone of inspiration, which enhances imagination and creativity. Its own spirit is at times that of a child; spontaneously playing, dashing color wherever it pleases. Carrying this imaginative spontaneity into the realm of your life can bring strong creativity.
