You should be careful when buying jewelry. The most important thing is not to buy fake or inferior goods. At that time, I also compared several jewelry brands, and later I chose gemologist Lao Xu. It turns out that I didn't make the wrong choice. Its jewelry has an appraisal certificate to ensure fidelity and quality. Especially their after-sales service is really amazing. There is no reason to refund after 7 days, and they support lifelong maintenance. There is a special reception service for jewelry cleaning in the later period, which is so worry-free.
