The whitening of gold bracelets is not necessarily worthless, but it is important to repair them in time. If the gold bracelet has white spots or fades, it is recommended to take it to the jewelry store for cleaning in time.

Reasons for white spots or fading of gold bracelets may include:

1. Exposure to or corrosion by "mercury" will produce white spots.

2. Friction with platinum jewelry will make a layer of white platinum attached to the surface of the gold bracelet.

3. During wearing, the gold bracelet is corroded or dyed by other white metals due to contact with chemicals.

If the gold bracelet has white spots or fades, it is recommended to take it to a jewelry store for maintenance. Generally speaking, the better the fineness of gold, the less likely it is to fade. If the gold bracelet has faded or white spots appear, the gram weight of gold may be reduced after thorough cleaning, which may affect the price of gold.

In a word, repairing the gold bracelet in time can keep its value and beauty.
