In particular, it has a strong power to improve work luck, cultivate concentration, judgment, and decision-making skills, and support the achievement of goals. Tiger Eye, the "stone of financial luck," "stone of prosperous business," and "stone that brings good luck," is ideal for business people and company executives to wear. However, it is not a stone that brings good luck, gets money, or achieves success just by being silent. It also has a strict aspect that requires the owner to strive, so it may be better not to wear it with a half-hearted feeling. Although it has a strict nature, once it recognizes the owner's efforts, it will become a reliable supporter. *Because it is a natural stone, the color and pattern may differ even for the same stone. *The color may differ from the actual color depending on the lighting.
