Is it normal for a modified watch bracelet made of 925 sterling silver to show black marks on the wrist when worn?

The black marks that appear when you use the watch chain are a completely normal phenomenon. Please don't worry. This is precisely a natural characteristic of 925 silver material.

🧪 Why do black marks appear?

The silver chain turns black mainly because it reacts with sulfur. This is usually caused by two reasons:

· Natural oxidation: Silver reacts with sulfides in the air to form a black silver sulfide film on its surface.

· Sweat contact: Human sweat also contains sulfur. When it comes into contact with silver, it will leave a black mark. This is actually silver protecting you, indicating that it is "absorbing" substances that are harmless to your body on your behalf.

✨ How to clean and maintain?

To restore the luster of the love chain, you can try these methods:

· Daily wiping (most recommended) : Use a dedicated silver polishing cloth to directly wipe the blackened area. The effect is immediate. Remember not to wash it with water, otherwise the medicinal effect of the cloth will be reduced.

· Gentle cleaning: Squeeze toothpaste onto a soft-bristled toothbrush, dip it in water and gently scrub the chain. Then rinse it with clean water and dry it.

· Kitchen tip: Line a bowl with aluminium foil and place a chain inside. Sprinkle baking soda over it and pour in hot water to soak for a few minutes. The black substances will "transfer" to the aluminium foil. Take it out, rinse it clean and dry it. It will be as shiny as new.

To delay darkening, please pay attention to:

· Keep dry: Remove it promptly after sweating from bathing, swimming or exercising to avoid contact with chemicals.

· Sealed storage: When not in use, wipe off sweat and grease with a dry cloth and put it in a sealed bag to isolate from air.

· Wear it with confidence: In fact, human body oils can form a protective layer, which can actually slow down oxidation. However, for those with slightly acidic sweat (commonly known as "acidic constitution"), the oxidation rate will be slightly faster.
