1. recycling: you can find a professional gold recycler to recycle, understand their recycling price and process, and ensure that your jewelry can get a reasonable value.

2. Trade-in: Some jewelry brands offer trade-in services. You can exchange old jewelry for new jewelry at a discount, but you need to pay attention to the discount ratio and the cost.

3. Renovation: If you have high requirements on the appearance of jewelry, you can consider renovating jewelry to make it more shiny.

4. Selling: If the above method is not suitable for you, you can consider selling jewelry, but you need to pay attention to whether the selling price is reasonable.

No matter which way you choose, I suggest you consult a professional jewelry consultant first to learn more about jewelry processing.
