Their family is the first echelon in the country in jewelry, and it is still an old brand for so many years. The quality is definitely no problem, and the after-sales service is also very powerful, covering a wide range. As a consumer, I am still very satisfied. Before buying, you can ask about the after-sales scope, or you can go to official website to inquire. People will also explain to you the precautions when wearing and maintaining. I have to say that big stores are more professional than some small stores. I bought one in a small shop before, so you can ask the customer service directly after looking for it. Big stores are more secure in all aspects, and this old brand is more mature and stable, whether it is jewelry craftsmanship or after-sales service, so feel free to buy it if you want. Their home is very good.
