What's with the black wrist on the silver bracelet?

The wrist on the silver bracelet turns black for the following reasons:

The blackening of the silver bracelet has nothing to do with the body itself. One reason why bracelets turn black is natural oxidation. Another reason is that it may be caused by long-term contact with sweat. Sweat contains sulfur, so it will change chemically and turn black after a long time of contact. Another reason is that if you often come into contact with some acidic or sulfur-rich substances, it will also lead to black silver ornaments.

Wear other ornaments on this wrist wearing a silver bracelet or wear several delicate bracelets on one wrist, which will collide or rub, and the silver bracelet will slowly turn black after rubbing.

Method for prevent silver ornament from blackening

1, surface treatment: this is an industrial method, which is not easy for individuals to adopt.

2. Surface coating treatment: coat a layer of transparent paint film on the surface of jewelry to isolate silver from the outside air. Ordinary wearers can apply colorless and transparent nail polish to jewelry. This method is particularly simple and does not affect the luster of silver jewelry. The time interval of applying nail polish or transparent paint film depends on the specific wearing situation of the wearer.

Because of the different working environment, it can be applied once a week for those who wear it quickly, and once every half a month or longer for those who rarely touch hard objects or wear jewelry to do housework. Jewelry that is not used for a long time should also be coated on the surface.

3. Always keep the silver jewelry clean and dry. Try not to let silver jewelry come into contact with sulfur-containing chemical gases, and don't clean silver jewelry with sulfur soap. Silver jewelry should be stored in a sealed and dry place when not in use.
