If you choose a crystal bracelet, you must choose a pure natural brand-new product. As I said upstairs, pure natural brand-new crystal is better for human body and will not radiate. It is not recommended to wear tea crystal products here, because tea crystals are more likely to be colored by radiation.
In the face of many crystal varieties, if your price is within 100, you can choose white crystal, obsidian and so on. The quality of these products at this price can be the best.
If the price is less than 500, you can choose garnet, moonstone, colored hair crystal and other products, and the quality at this price is better.
If the price is above 500, you can consider choosing tourmaline, rabbit hair crystal, green ghost and other products.
If the price is above 1000, it is recommended to consider tourmaline and Shuzulai.
Other crystal products are not recommended. Personally, I think these are better for mothers in their 60 s.
Garnet, moonstone, tourmaline, Shujulai and other crystal products are especially recommended.
Hand experience, I hope it will help you, and I wish you good luck!
