If Lao Fengxiang's hard gold jewelry makes a crisp sound, it may not be fake, but it can't be judged by this.

Hard gold jewelry is the product of Lao Fengxiang, which is usually harder and more wear-resistant than other types of jewelry. Hard gold jewelry may sound more brittle than other jewelry, but it doesn't necessarily mean it's fake. In order to further confirm the authenticity of hard gold jewelry, other methods need to be used for testing.

If you have any questions about the hard gold jewelry you bought in Laofengxiang, I suggest you go to a professional jewelry appraisal agency for testing, or contact Laofengxiang's customer service for consultation.
