I suggest choosing 2 or 3 pieces to wear. Obsidian is cheap and not easy to fake, and the effect is excellent. Double rainbow eye obsidian is also a few dollars each. I suggest buying obsidian first.
Agate is not easy to buy fakes, so it is also recommended.
As for the other three kinds of wood products, Bodhi can be given priority, and it is a treasure in Buddhism and medicine. Daphne and rosewood may have inferior products (such as dead wood or moth-eaten), which greatly reduces their efficacy. The identification method can be judged by the smell, and the top grade wood will have an elegant fragrance. And it will change with the time of the day and the condition of the wearer. After a long time, the fragrance will not disappear, but will become more intense. This is my personal suggestion for your reference.
