The classification of crystals can be divided according to the sign of their energy. They are positive energy crystals and negative energy crystals. Positive energy crystals are radioactive, and negative energy crystals are absorbing.
The frequency emitted by radioactive crystal is high frequency, and the energy it emits can attract magnetic fields. General crystals are radioactive crystals. For example, amethyst, etc., they can frequently emit positive energy, input pure energy into the wearer, and have the effect of purifying human energy!
The frequency that the absorbent crystal emits is low-frequency, it can absorb the negative energy discharged from the human body and nearby, and play a role in energy conversion. Black crystals are all absorbing crystals.
