There are two basic energies that stones possess. They are either projective, or receptive.
Projective stones are masculine in nature and can be used in healing, protection, intellectual powers, luck, success, will power, courage, and for self-confidence. Projective stones tend to be strong, bright, forceful.
Receptive stones are feminine in nature and can be used for soothing, love, wisdom, compassion, eloquence, sleep, dreams, friendship, growth, fertility, prosperity, spirituality, psychism, and mysticism. Receptive stones are calm, inward, peaceful.
