Is it too expensive to buy in Liu Fu? I'm not sure how to join Liu Fu jewelry, but I'm sure the purchase price of Liu Fu jewelry is the same as that of other regular jewelers. Joining Liu Fu requires an initial fee. One of the services provided by Liu Fu for franchisees is to select the goods specially provided for Liu Fu jewelry or pick up the goods in the exhibition hall designated by Liu Fu. Merchants who are not affiliated with Liufu cannot choose these goods.

There are several possibilities in your situation.

First: Maybe this Liu Fu jeweler went to Baohengda to buy goods (a jeweler can't get goods from one manufacturer, because every manufacturer has its superior and inferior products) and forgot to stamp the word "Liu Fu". (Generally, you type in the factory, but merchants generally don't type or print. )

Second: If this merchant recycles the customer's jewelry or provides a replacement service (referring to the jewelry bought in non-Lukfook jewelry), if a relatively new jewelry is recycled or replaced at that time, then this Lukfook merchant thinks that this product can be sold again, and the other party may have refurbished it and put it on the counter. Moreover, this product is "Bao Hengda" (so you don't have to take the old jewelry to the manufacturer for disposal, saving the labor cost of the merchant)

The "K" behind the earrings generally refers to the manufacturer's code or something else, and it's nothing. There may be more than one manufacturer. If you still have the warranty or invoice of the earrings you bought at that time, you can check the weight. If the difference is not big (it may be worn for several years, or it may be less than 0.00g), you can ask for after-sales service (unless it is stated in the documents at that time that replacement is not allowed after sale, in general, replacement is one of the after-sales services).
