What Is the Difference Between 925 Silver and Sterling Silver?

Customers ask me this regularly: is there a difference between 925 silver and sterling silver? The answer is simple: no, they are exactly the same thing. The two terms refer to the same material, just from different angles.

What Does 925 Mean?

The marking “925” is a hallmark you find stamped on a silver piece of jewellery. The number refers to the silver content: 92.5% pure silver. The remaining 7.5% consists of other metals, usually copper. That small addition is necessary because pure silver is too soft to make jewellery that can withstand daily wear.

The “925” stamp is essentially a quality guarantee. When you see that number on a piece, you know it is genuine sterling silver and not a cheap substitute or inferior material.

What Is Sterling Silver?

Sterling silver is the name for that standard alloy of 92.5% silver and 7.5% copper. The term “sterling” has historical roots and was used centuries ago to describe silver coins and tableware that met a certain purity standard. Today it is the international standard for silver jewellery.

So whether you see “925 silver” or read “sterling silver” in a product description, you are looking at the same material.

What Is Fine Silver?

There is also fine silver, marked as 999 or 99.9% pure silver. Fine silver is softer and more malleable than sterling silver, making it less suitable for jewellery worn every day. It is sometimes used for special occasion pieces or coins, but not for everyday rings or bracelets. It tarnishes more slowly than sterling silver, which is an advantage, but its lower durability outweighs that benefit for wearable pieces.

Does Silver Tarnish?

Yes, sterling silver tarnishes. This is a natural process where the silver reacts with sulphur compounds in the air, causing it to develop a dark or grey tint. This is not a defect, simply the nature of the material.

Fortunately, tarnished silver is easy to restore. A few tips:

• Polish your silver jewellery regularly with a soft cloth or a dedicated silver polishing cloth.
• Store silver in a sealed box or pouch to limit exposure to air.
• Avoid contact with perfume, sweat, sunscreen and cleaning products.
• Remove your silver jewellery before washing up or cleaning the bathroom.

Is 925 Silver Suitable for Sensitive Skin?

For most people, sterling silver is perfectly comfortable to wear. The small amount of copper in the alloy can occasionally cause a reaction in people with very sensitive skin or a copper allergy. If your skin turns slightly green where a silver ring rests, that is the copper reacting with your skin’s natural acids. It is harmless but can be annoying. In that case, a higher quality silver or a different metal might be a better choice.
