Lao Fengxiang is a well-known jewelry brand, and the jewelry she usually sells is professionally tested and certified. If the merchant claims that this bracelet is Hetian Jade A, it should be tested and certified accordingly.
However, if you have doubts about the authenticity of the bracelet you bought, I suggest you take the following measures:
1. Check the purchase voucher: check whether you have the purchase voucher, and whether the details of the bracelet, such as material and weight, are indicated on it. Vouchers should also have the seal or signature of the merchant to ensure their validity.
2. Consult a professional organization: you can take the bracelet to the local jewelry testing institution for testing. These institutions usually provide paid testing services and will issue authoritative testing reports for you.
3. Contact the merchant: If the bracelet has a searchable security code, you can check it through Laofengxiang official website or the in-store service staff. In addition, if you have any questions about the purchased goods, you can also contact the merchant directly for consultation and solution.
In short, if you have doubts about the authenticity of the bracelet you bought, you'd better contact the merchant or professional testing institution directly for confirmation.
