1, emerald. Jade has played an irreplaceable role in the hearts of China people since ancient times. Its aura not only represents the beautiful meaning of sending blessings and gathering blessings, but also is the "amulet" for turning disasters into blessings. Jade Guanyin and Jade Buddha, in particular, are full of people's desire to ward off evil spirits and eliminate disasters. Jade can also be worn in the bath, which can also avoid dehydration of jade due to excessive temperature. But it must be grade A jade, so it won't affect when it meets water.

2. Obsidian. Obsidian is probably the most commonly used amulet besides jade. As one of the commonly used gems in beads, it is not only a common treasure to ward off evil spirits, but also has a good meaning of peace and good luck. The point is, it is not expensive.

3, beeswax. Beeswax comes from trees. It is formed by resin dripping on the ground and then after years of geological activities. If it comes into contact with clear water, it has no effect at all. And washing is actually a step of beeswax maintenance. Usually when we wear beeswax, it is inevitable that we will be contaminated with dust and sweat. This requires soaking beeswax in water and rubbing it by hand, and then wiping off the water stains with a soft cloth. Finally, don't forget to put some olive oil on it, and then wipe it off later, and it will be as bright as new.
