Black onyx stabilizes the mind, serves as a powerful amulet, and enhances concentration. It also protects against negative external energies and helps to ground the wearer. It allows you to deal with things calmly and improves self-control, judgment, and decision-making. You can steadily move forward towards your goals without being swayed by the opinions of others. It is especially recommended for those who are easily influenced by others or who have difficulty persevering. Thank you for viewing.
