People have always known about the healing properties of gemstones and minerals. Early civilizations were very aware of the power of crystals.  They used crystals in the ritual, talisman, jewelry and armor. Semi-precious stones accumulate the energy of the Sun, the Moon, and the oceans. When you come in contact with the crystals, they connect you to the Earth and transfer the healing energy to your body. Quartz, opals, and amethyst are the most popular stones used in crystal healing. The practitioner places the crystals on different parts of the body. The placement of crystals usually corresponds with the seven chakras but doesn’t have to.  Apart from` healing sessions, you can wear a crystal close to the skin as a healing amulet. Place crystals around your house to purify and charge your environment with positive energy.
