Whether you are shopping for a meaningful gift or looking to upgrade your everyday jewelry stack, you have likely seen the stamp "925" on silver jewelry. But what does it actually mean? Is it real silver? Will it irritate sensitive skin?

In this guide, we break down everything you need to know about 925 sterling silver, from how to identify the real thing to how to keep it shining for a lifetime.

What is 925 Sterling Silver?

925 Sterling Silver is an alloy made of 92.5% pure silver and 7.5% other metals, typically copper. It is the global standard for high-quality silver jewelry.

Pure silver (99.9%) is incredibly soft—so soft that if you made a ring out of it, it would bend and warp just from the pressure of your hand. To make the metal durable enough for everyday wear, artisans blend it with a small amount of harder metal (the 7.5%). This creates a strong, lasting piece of jewelry that retains the brilliant, icy shine of pure silver.

Is 925 Sterling Silver Hypoallergenic?

Yes, genuine 925 sterling silver is hypoallergenic and completely safe for sensitive skin, provided it does not contain nickel.

The dreaded "green finger" or itchy earlobes are usually caused by cheap brass or nickel fillers used in low-quality fast fashion jewelry. Because true 925 sterling silver uses copper as its strengthening alloy rather than nickel, it is an excellent choice for sensitive skin. At Itz Luxury, all of our Sterling Silver Rings and Butterfly Necklaces are guaranteed 100% nickel-free.

Does 925 Sterling Silver Tarnish?

Yes, all genuine sterling silver will eventually tarnish when exposed to air, moisture, and sulfur. However, this is a natural reaction, not a sign of poor quality, and it is easily reversible.

Tarnishing is simply a chemical reaction on the surface of the metal. The good news? Wearing your jewelry is actually the best way to prevent it! The natural oils in your skin help protect the silver and keep it polished.

Things that accelerate tarnishing:

• High humidity and ocean air
• Chlorine from swimming pools
• Direct contact with perfumes, lotions, and hairspray
• Sweat from heavy workouts

How to Clean Tarnished Sterling Silver

If your silver starts looking a little dull or dark, do not panic. It takes less than five minutes to restore its original brilliance.

1. The Polishing Cloth: For light dullness, a simple microfiber jewelry cloth is all you need. Gently rub the piece in back-and-forth motions (not circles, which can magnify tiny scratches).
2. The Soap and Water Method: For heavier dirt, mix a few drops of mild dish soap with warm water. Use a soft-bristled baby toothbrush to gently scrub the jewelry, then rinse and pat completely dry.
3. The Baking Soda Method: For severe tarnish, line a bowl with aluminum foil (shiny side up). Place your jewelry inside, sprinkle a tablespoon of baking soda over it, and pour in boiling water. The tarnish will magically transfer from your jewelry to the foil! Rinse and dry thoroughly.

How to Tell if Sterling Silver is Real: 3 At-Home Tests

If you are buying jewelry online, you want to ensure you are getting what you paid for. Here are three ways to verify your piece:

1. The Hallmark Test: Look for a tiny stamp on the inside of the ring band or the clasp of the necklace. It should read "925", "S925", or "Sterling".
2. The Magnet Test: Genuine silver is non-magnetic. If you hold a strong magnet to your jewelry and it snaps to the metal, it is likely steel or nickel covered in fake silver plating.
3. The Smell Test: Real silver has no scent. If your jewelry smells metallic, brassy, or like copper coins, it is not pure 925 sterling silver.
