Copper decoration: Copper reaction will make the skin appear green. The jewelry we wear may not be pure copper, but the copper content is also sufficient to react with the skin. Especially when some human bodies have strong body chemistry, they are more likely to produce spots.

Sterling silver jewelry: Sterling silver contains 7.5% copper, but most of the spots caused by sterling silver jewelry are black and occur after the metal and air react to turn black. Some pure silver jewelry will be coated to prevent air oxidation, but the coating will gradually peel off over time.

Gold jewelry: Gold itself hardly leaves any stains on your skin, but other metals mixed in gold will. Copper, nickel, and silver are mixed with gold to change the color tone of gold and make it harder, reducing its cost. But because k gold is mixed with other metal substances, some people may be allergic to these metal substances. If they are allergic to k gold, it is recommended to purchase 24k pure gold.

Nickel jewelry: If you are allergic to nickel, it leaves you with more than just stains. Wearing nickel jewelry can cause itching, redness, and even yellow water to flow out of your skin.
