Does anyone suffer from metal allergies?
I myself have suffered from severe metal allergies.
In particular, piercings are more susceptible to allergies because, unlike fingers or arms, ions can easily penetrate them.

In this article, we will focus on earrings that are particularly likely to cause metal allergies and look at countermeasures and solutions!

First, let's look at the causes of metal allergies.

When metal comes into contact with sweat or bodily fluids, metal ions are released.
The metal ions bind to proteins in the body, causing an allergic reaction.
The reason you experience that extremely painful itching and rash is because this is what is happening inside your body and with the metal.

Now that you understand the principles of metal allergies, let's consider the causes of allergic reactions to silver 925 earrings.

Do 925 silver earrings cause metal allergies?

To put it simply, the material 925 silver can cause allergies.
However, in most cases, the allergic reaction is not to silver, but to other metals such as nickel, cobalt, and aluminum, which are used as alloys and make up 7.5% of the silver content.

If you are suddenly told that it is a metal other than silver, it's hard to know what to do...
From here, we will take a closer look at the material called silver 925.

Are there two types of silver 925?

Did you know that there are two types of silver 925?

Made of 92.5% silver and 7.5% nickel and aluminum
①Silver 925

Made of 92.5% silver and 7.5% copper
②Sterling silver

Both ① and ② are 925 silver, but they are called differently depending on the metals they contain.
Furthermore, sterling silver is an extremely durable material that ages and hardens, meaning it becomes stronger the more it is used, which is why the two grades are distinguished in the jewelry industry.

If you have a metal allergy to a 925-stamped item, it is most likely due to a reaction to nickel, cobalt, aluminum, etc., which are included in the 7.5% of items listed in item 1. (There are also cases where the item is plated with 925 silver, but we will not discuss this here.)

② Quite a few people have tried sterling silver and found that they no longer experience any allergies.
I am one of them.

Silver is classified as a hypoallergenic metal, so if you have an allergic reaction to 925 silver earrings, we strongly recommend that you don't give up and try sterling silver earrings.

How to distinguish between 925 silver and sterling silver?

A silver ring and a square silver ring are placed on top of a white box with the Nine Nine logo embossed on it. The photo has a chic feel with the design of light and shadow.

Unfortunately, it is impossible to tell the difference between 925 silver and sterling silver just by looking at it.
Both are stamped with 925, so they look almost identical.
You can tell the difference by analyzing the ingredients, but you can't do that when you're shopping.

So what should I do???
I'm also struggling with this issue.

It's already being sold in a jumble, so I think the only thing you can do is ask the stores that sell it.

Ask the store, "Is this sterling silver?"

  • If you immediately answer "Yes!", it's probably sterling silver.
  • Yes! It's silver bullion! In that case, it would be sterling silver.
  • Well, maybe! If so, it's possible that you don't know what sterling silver is. That's worrying.
  • No! → It is not sterling silver, it is either silver 925 or silver 925 plated.

I might be able to make a decision depending on the response...

Be careful with the posts and backs of your earrings!

Another thing you should not overlook is the post and back of the earring.
Since the earrings and posts are parts that come into direct contact with your ears, it is safest to choose sterling silver.

Even if a product is labeled as 925 silver, if it is too cheap or made overseas, it may not even be plated with 925 silver or may not even be 925 silver at all.
We hope that this will help you to gain a correct understanding of silver 925 so that you will avoid purchasing from such sellers.

All Nine Nine earrings are made from sterling silver.
