Now that you have some gemstones you will want to educate yourself on how to care for your precious rocks. Your gems, crystals, jewelry, pendulums, basically anything around you, or on you, can attract positive and negative energy and hold that energy unless the object is cleansed. I personally favor smudging my crystals with sweet grass, sage, cedar and tobacco. There are many different methods of cleansing your gemstones. Some stones enjoy water baths others moon or sun light cleansing. Although some stones will fade in sunlight such as amethyst. Whatever way you feel intuitively drawn to I would recommend to use, but there are also many websites with detailed information in regards.
Sun or Moon Cleanse:
Place your gems, crystals, pendulums, jewelry, all types of objects, in a place where they will be fully exposed to the energizing rays of the sun and moon. Even if the day is cloudy or you cannot see the moon, their rays will energize the stones as long as they are directly exposed to these elements of nature. They will normally be cleansed within 24 hours of exposure.
Place your gems, crystals, jewelry, whatever, in the earth, either directly into the earth or you can place the gems and crystals into a cloth covering, preferably a natural fabric such as cotton or wool or silk. Leave the gem or crystal buried for at least 24 hours to ensure that they become fully re-energized. If possible, find a spot where the soil is not being spread with chemicals through fertilizers or pesticides. This cleanses all negative energies and re-energizes the stones.
If you live where you have access to good clear well water that is guaranteed to be free of chemicals, or running water from a creek or river that you know is not polluted, place your crystals and gems in a small container, and let the water run over them, preferably for at least two hours. This will cleanse and re-energize your gems and crystals. Please do not use tap water, since it is full of chemicals. Be careful though because certain stones will actually dissolve in water, e.g. Red Selenite.
