Quartz or mountain crystal regulates negative energy, cleans and neutralizes harmful emissions of the environment. It helps us relax and fulfill our desires. It clears our mind and helps to overcome fears, strengthens brain functions, stabilizes the heart and energy flow. It helps well with overcoming neuroses and hormonal problems.

If we use it with other crystals, it increases their strength. It can also be used to clean other crystals.

Cleaning:

• Because quartz binds negative energy, it needs to be cleaned more times than other crystals (recommended at least once a week)
• The crystal can be cleaned under running water.

Charging:

• Charge the crystal by exposing it to the moonlight.
