Nickel allergy is a recurring topic when talking about silver jewelry.
Nickel allergy is a contact allergy that is often caused by zippers, buttons, watches, jewelry and similar accessories that are worn close to the skin for a long time through that the skin absorbs nickel that has been released. The skin gets red itchy rashes, lumps and swelling. The skin may become dry and cracked. No one is born with a nickel allergy, but once you have it, you will have it forever, and you must avoid nickel to avoid the rash. This can of course be very difficult because all metals, including gold and silver, can contain nickel, mainly in the form of impurities. Nickel allergy is not hereditary and not contagious.
Below I explain a little more about what nickel is and how to test a piece of jewelry.
What is nickel?

Is there nickel in real gold?
Gold is an element and contains no nickel. To get red gold and rose gold, you add copper, the more copper, the redder the color, and usually a smaller amount of silver and possibly other metal. White gold is not a base metal but a mixture of gold, palladium, copper and silver. People who are allergic to nickel may have difficulty wearing certain types of white gold, as a small amount of nickel has previously been used in the alloy. However, nickel in the alloy of white gold was banned in the 80s.
The most common 18K gold alloy in Swedish trade, "Swedish red gold", has a gold content of 75%, silver 8-9% and copper 16-17% , while in many other countries you have equal parts silver and copper in the corresponding, which is therefore yellower, "yellow gold".
