2. Red agate is not suitable for people who are too weak because the five elements belong to fire and the five elements belong to soil. For example, people who are seriously ill or weak, if they wear red agate jewelry with strong fire, will lead to a sharp decline in their physical condition, which is not conducive to health.
3. The first is to avoid collision. After all, although red agate has high hardness, its texture is very brittle. Once it collides with a hard object, it is easy to be damaged, broken and cracked. The second is to avoid exposure. After all, at high temperature, precious stones will expand with heat and contract with cold, which may destroy their internal structure. Finally, the red agate ornaments should be kept away from acid and alkali. High-strength acid and alkali will corrode the red agate and cause irreparable damage.
