Black Agate helps you to recognize your weaknesses so you can work on them. It brings out from the subconscious those layers where unrealized aggression, anger or irrational fears still lie. For this purpose, black agate should be worn for at least a month. And those who no longer have these qualities will calm down, relax and reveal the truth. It is most useful with white or off-white stripes, because it can no longer even be considered an agate if it is monochrome without patterns. For people living an ordinary life, it will provide protection from negative environmental influences, provided that you do not initiate them with your own personal characteristics, it will strengthen the immune system. It is useful for colds or those prone to colds. It helps to concentrate the mind, to think rationally, hard and sharp. Strengthens protection against negative environmental influences, provided you do not involve yourself with your character and behavior.
