1, local jewelry stores and gold stores generally sell tourmaline, so it is also appropriate to try it on directly. The disadvantages are too high price, too little quantity, low selectivity and poor addition ratio;

2, jewelry exhibition, mineral exhibition, this large-scale exhibition will have a lot of jewelry merchants gathered, a lot of things, and the price is not high. You can bring friends who know how to do things. The disadvantage is that these businesses can't find anyone after two or three days, and it is easy to buy fakes at the exhibition;

3, online shopping, online shopping tourmaline has strong selectivity, and the addition ratio is also good. The disadvantage is that you can only look at pictures, and you can only see the real thing after mailing.

Jewelry is not cheap, and the quality is uneven. I suggest you choose a stable merchant and buy it for a long time, which will make people feel at ease, cheap and good friends.
