Jewelry brand stamp is not necessarily the same brand, every product is exactly the same! For example, some goods are often engraved with the logo or English abbreviation of jewelry brands because of the narrow printable area! Like Jinliufu Jewelry, most stores in China belong to franchise stores, and the supervision of franchise stores in different regions is not necessarily the same. The products of Jinliufu Jewelry Store are not necessarily the products of Jinliufu Corporation, but many of them may be produced by other factories or provided by two other suppliers! Often just a carved steel seal! So in China, unless the goods you buy are brand-specific, that is, patents, you must have a patent number to call them patents. Otherwise, it is basically the same, just pay attention to the following points: whether the content of 1 is qualified; Whether the gem certificate is in conformity with the goods; Whether the material is consistent with the certificate of steel seal; If the brand has no exchange and repurchase business, then in fact, the so-called after-sales service can help you repair the ring in any jewelry store as long as you spend money! It doesn't have much practical significance!
