The unique ability of crystals to absorb information and energy enables them to absorb the energy of the earth for thousands of years, becoming a gemstone with a lot of energy. Energy is enough to affect our luck, health and emotions. Because of this, different people may leave a good or bad magnetic field after touching it. Therefore, in order to prevent people from unknown sources from affecting their own magnetic field, crystal jewelry must be degaussed (also known as purification) after being bought from a crystal shop.
In addition, the crystal will also absorb the negative energy you emit. When a certain amount of negative energy is stored, the crystal will become dim and cloudy. Regular purification of the crystal can eliminate the negative energy stored in the crystal, so as to keep the crystal bright, so that the emitted energy and its efficacy can be exerted.
If the crystal has not been purified for a long time, the negative energy will continue to accumulate, which will gradually block the original aura and efficacy of the crystal. It may even cause the crystal to lose its efficacy permanently. Some people will commonly call this situation "the crystal is dead". So we can see the importance of degaussing and purifying crystals.
The principle of purification or degaussing is to dissolve the negative energy in the crystal and turn it into harmful energy. Very few crystals can do this. Most crystals can only absorb and transfer negative energy to themselves, but this is not in line with the principle of purification. Because the crystal that has absorbed negative energy is itself the object to be purified.
