Gold and silver jewelry stores such as Saturday Fook, Saturday Xin, Luk Fook Jewelry and other gold and silver jewelry stores are often chain franchise stores. Only the brand is authorized for exclusive use. Generally, there is no requirement that the products sold must be developed from the brand. Purchases, so products with different trademarks are often the result of purchases from different manufacturers. Under normal circumstances, these specialty stores often deliberately affix the Saturday Fortune trademark. The situation you mentioned is often seen on non-gold products such as jade bracelets, palladium jewelry, diamond pendants, and diamond rings.
