Is the necklace out of warranty now? If it is within the warranty period, you can take the necklace and related materials to the jewelry store for repair. Generally, regular jewelry stores have such after-sales service, which can be cleaned for free after repair, and will glow when you buy it back.

If the necklace can't be repaired, you can consider changing money, adding some old gold handling fees on the basis of the old gold, and making up a certain price difference for a new piece of jewelry.

Necklace storage method

1, jewelry storage box, convenient and practical.

Jewelry boxes should be a must-have item for every housewife. Most jewelry boxes on the market are beautifully designed and have diverse functions: multi-layer, with mirrors and photo frames ... Necklaces, earrings, rings, brooches, scarves and other small ornaments have special places, which are not only organized, but also very convenient to take.

2, jewelry storage rack, novel and beautiful.

Besides hiding jewelry in jewelry boxes, it is also a fashionable way to show all kinds of beautiful jewelry. Shiny ornaments such as necklaces and earrings are hung on the jewelry rack, and a work of art is born at the same time when the storage is completed.

Step 3: straws

Necklaces that are often worn together are easily intertwined, and at this time, straws used for drinking drinks can also be used as tools for storing ornaments. Pass the necklace through one end of the straw and lock the outside of the straw. Then arrange the straws neatly one by one, and the necklace can be stored well.
