Not recharging them at all
When crystals are not recharged after specific days, they tend to accumulate a lot of dust and unwanted energies which leads them ultimately to beak or shatter. Clearing is not a process of removing negativity from a crystal. It is a process of returning the crystal to its natural base resonant frequency, to ensure it is able to take in as much energy through the Earth’s EMF as it is used to doing.
