.925 Sterling Silver: What It Means, Why It Tarnishes and How to Care for It
Ever notice a small .925" stamp on your James Avery ring, necklace or charm and wondered what it means?
It's one of the most common (and important) markings found on sterling silver jewelry.
We're here to break down the basics of .925” sterling silver, along with practical tips to help keep it looking its best for years to come.
What is .925 Sterling Silver?
When you see .925 sterling silver, that means the design is made up of a silver alloy that contains at least 92.5% pure silver.
People often assume higher silver content automatically means better jewelry, but that's not always the case. 99.9% pure silver has a beautiful bright appearance, but it's also quite soft.
By combining silver with other metals, our artisans create an alloy that is better suited for jewelry that will be worn, enjoyed and passed down over time. The added metals help improve strength, durability and the ability to hold intricate design details.
At James Avery, we alloy our sterling silver with copper rather than nickel. This gives us a durable sterling silver alloy while avoiding the use of nickel in our silver designs. Copper also allows us to add that signature oxidation to highlight and contrast our designs are known for.
It’s important to note that sterling silver does tarnish over time, but regular polishing and care can help maintain its brightness.
From Pure Silver to Sterling Silver: Made in Our Texas Foundry
At James Avery, the details matter. Unlike many jewelry companies, we don’t source our sterling silver from other manufacturers. All of our sterling silver is made by our own artisans.
In our Texas foundry, pure silver is carefully alloyed with copper to create the sterling silver used in many of our designs. This process helps transform the soft, precious metal into one that's better suited for everyday wear while maintaining the bright appearance sterling silver is known for.
Watching the process is a little mesmerizing. Molten silver glows as it's blended, poured and transformed into sterling silver castings that will later become your favorite designs.
It's one of the many ways our teams combine artistry, craftsmanship and attention to detail, carrying on a tradition that has been part of James Avery for generations.
What the .925 Stamp Means
The number ".925" is a purity mark.
It tells you that 925 parts out of every 1,000 parts of metal are silver. That's where the term 92.5% silver comes from. You'll often see markings such as:
- .925
- 925
- Sterling
- STER
These marks all generally indicate the same sterling silver standard.
Look for sterling silver marks:
- Inside a ring
- Near or on a clasp
- On the back of a charm or pendant
- In another discreet location on the jewelry
So is .925 Sterling Silver Real Silver?
Yes, .925 sterling silver is real silver.
The silver content remains the primary component of the alloy. The additional metals simply help make silver more practical for daily wear. In fact, sterling silver is one of the most widely used precious-metal alloys in jewelry because it balances silver content with everyday durability.
Sterling Silver vs. Silver-Plated Jewelry
Another common point of confusion is silver-plated jewelry.
Solid sterling silver contains silver throughout the metal alloy itself. Silver-plated jewelry has a layer of silver applied over another base metal.
At James Avery, all our silver designs are made of solid .925 sterling silver – meaning we never plate or “fill” our jewelry. Not only does this mean our designs don’t “flake off” over time, but it also means every design retains the market value of sterling silver rather than diminishing over time, like most plated and costume jewelry.

How to Care for Sterling Silver Jewelry
If you haven’t owned a sterling silver piece before, tarnishing can seem alarming. However, tarnish is a normal part of owning sterling silver jewelry and is easy to clean.
Tarnish is a Natural Surface Reaction
Sterling silver can react with sulfur compounds and other environmental factors, creating a thin darkened layer on the surface.
Tarnish may appear:
- Yellowish
- Gray
- Brown
- Dark gray
- Black
This doesn't automatically mean your jewelry is damaged, poor quality or fake. It's simply one of the natural characteristics of sterling silver.
What Contributes to Tarnish?
Many factors can influence how quickly tarnish develops:
- Humidity
- Air Pollution
- Perspiration
- Skin Oils
- Cosmetics
- Lotions
- Fragrances
- Household Chemicals
- Improper Storage
- Long Periods Without Wear
How to Recognize Designed Oxidation
Often, intentional oxidation:
- Appears consistently in recessed areas
- Follows a deliberate pattern
- Sits alongside polished raised surfaces
- Looks purposeful rather than uneven
If you're unsure, it's always best to review the product details or speak with a James Avery Associate.
How to Keep Sterling Silver from Tarnishing
While tarnish can't always be prevented completely, a few simple habits can help slow it down.
Our top tips:
- Put jewelry on after applying and letting lotions, fragrance and cosmetics set or dry
- Gently wipe jewelry after wear
- Remove jewelry before vigorous activity
- Limit exposure to harsh household chemicals
- Store each design separately whenever possible
- Keep jewelry in a dry environment
- Store sterling silver in an airtight baggie or container
How to Clean .925 Sterling Silver Safely
Before cleaning any jewelry, always take a moment to evaluate the complete design. Not only with this alert you to any issues, but care requirements can vary if a silver design includes:
- Gemstones
- Pearls
- Enamel
- Leather
- Ceramic
- Intentional Oxidation
Step 1: Start with a Polishing Cloth
Gentle polishing is often the safest first step.
Focus on exposed sterling silver surfaces and avoid excessive pressure while cleaning.

Step 2: Buff Gently
Once the surface has been polished, gently buff the jewelry to remove remaining residue and restore shine. Pay attention to recessed areas if the design includes intentionally oxidized details.
Our polishing cloth is two-sided, with a polishing side and a buffing side, making cleaning your sterling silver fast and easy.
Step 3: Use Mild Soap and Lukewarm Water When Appropriate
Some designs can be cleaned using mild soap, lukewarm water and a soft brush.
However, this method is not appropriate for every material, which is why checking the design's care requirements is important. You can find more information on our Care & Cleaning page.
Step 4: Visit A James Avery Store for Free Professional Cleaning
If you're dealing with heavy tarnish, uncertain materials, gemstones, pearls or intentionally oxidized details, professional guidance may be the safest route.
What Not to Use on Sterling Silver Jewelry
Skip Harsh Chemical Dips
Harsh dips may affect intentional oxidation, gemstones, pearls, enamel and other design features.
Avoid Abrasive Household Products
- Toothpaste
- Abrasive Powders
- Scouring Pads
- Rough Cloths
These products can scratch surfaces and remove intricate design details.
Avoid Over-Polishing
Remember, polishing removes a very small amount of material from the surface over time. Gentle, occasional care is better than frequent aggressive polishing.
Frequently Asked Questions About .925 Sterling Silver:
Does sterling silver rust?
No, rust typically occurs in materials containing iron. Sterling silver doesn't rust. Instead, it tarnishes or oxidizes, creating a surface reaction that often can be addressed through proper care or cleaning.
Is tarnish permanent?
In most cases, normal surface tarnish can be reduced through gentle polishing or appropriate cleaning methods. However, heavily tarnished jewelry or designs with special finishes may benefit from a professional evaluation. Our Store Associates are always happy to look at any of your James Avery designs and offer a free cleaning on up to 10 pieces at a time.

Can .925 sterling silver get wet?
Brief exposure to water does not automatically damage sterling silver. However, repeated exposure to moisture, chlorine, soaps and other substances may contribute to tarnish, buildup or wear over time.

Storing designs separately and removing jewelry before activities that may cause hard impacts can help reduce surface wear.
Why does sterling silver sometimes mark skin?
Occasionally, skin discoloration may occur due to factors such as moisture, cosmetics, body chemistry or reactions involving alloy metals.
A temporary green or dark mark does not automatically indicate that your sterling silver jewelry is fake.
Is .925 sterling silver hypoallergenic?

At James Avery, we alloy our silver with copper instead of nickel. Anyone with known metal sensitivities should review material information carefully and consult a medical professional regarding persistent reactions.
Is .925 silver the same as sterling silver?
Yes, .925 silver and sterling silver generally describe the same silver purity standard.
