Several jewellery allergies

Gold jewelry

Gold itself will hardly leave any stain on your skin, but other metals mixed in the gold will. Copper, nickel and silver and gold mix to change the color of gold, and make it harder and reduce its cost. Any of these metals will leave their mark on your skin.

The smaller the K (Karat) on gold jewelry, the lower the purity of gold and the higher the content of other metals. Some people don't respond when they wear 10K gold, but some people must buy 18K gold to prevent discoloration.

Sterling silver jewelry

Sterling silver contains 7.5% copper, but most of the sterling silver jewelry spots are black, and both occur after the metal and air react black. Some sterling silver jewellery will be coated with a coating to prevent air oxidation, but the coating will gradually fall off with long wear.

Nickel allergy

If you are allergic to nickel, it is not just a stain that is left to you. Wearing nickel-containing jewelry can make your skin itchy, red and swollen, and even yellow water.

Copper ornaments

After the copper reaction, the skin will be green. The jewelry we wear may not be pure copper, but the copper content is enough to react with the skin. Especially when some human body can have strong bodychemistry, it is more likely to produce spots.
