What Is Sterling Silver? Guide to Genuine 925 Silver Jewellery

Sterling silver has remained one of the world’s most loved precious metals for centuries. From elegant necklaces and timeless rings to luxury bracelets and heirloom jewellery, sterling silver combines beauty, durability, and affordability in a way few materials can match.
If you’ve ever wondered what “925 Sterling Silver” means or why it is considered the gold standard for quality silver jewellery, this guide will explain everything you need to know.
What Is Sterling Silver?
Sterling silver is a precious metal alloy made from:
- 92.5% pure silver
- 7.5% other metals (usually copper)
Because pure silver is naturally soft, it is not ideal for everyday jewellery. Adding a small percentage of strengthening metals improves durability while preserving silver’s beautiful appearance.
This is why genuine sterling silver is commonly stamped:
925
The number “925” indicates that the jewellery contains 92.5% pure silver, meeting the internationally recognized standard for sterling silver.

Why Isn’t Jewellery Made From 100% Pure Silver?
Pure silver (99.9% silver) is extremely soft and can easily:
- Bend out of shape
- Scratch during wear
- Become damaged through everyday use
Sterling silver was developed to solve this problem.
By combining silver with a small amount of other metals, jewellers create a material that remains beautiful while being strong enough for daily wear.
What Does 925 Mean on Jewellery?
One of the most common markings found on quality silver jewellery is:
925
This hallmark confirms that the piece contains 92.5% pure silver.
Other common sterling silver stamps include:
- 925
- S925
- Sterling
- Sterling Silver
A genuine hallmark is one of the easiest ways to identify authentic sterling silver jewellery.
Benefits of Sterling Silver Jewellery

What Is Rhodium-Plated Sterling Silver?
Many premium sterling silver pieces are finished with a layer of rhodium.
Rhodium is a rare precious metal from the platinum family that provides:
- Enhanced shine
- Increased scratch resistance
- Tarnish protection
- A brighter white appearance
At ZARSIK, many of our sterling silver jewellery pieces feature rhodium plating for a luxurious finish and lasting brilliance.
Does Sterling Silver Tarnish?
Yes, sterling silver can naturally tarnish over time.
Tarnish occurs when silver reacts with sulfur compounds in the air.
However, tarnish is completely normal and does not mean the silver is fake or poor quality.
Factors that can accelerate tarnishing include:
- Humidity
- Perfumes
- Lotions
- Household chemicals
- Improper storage
Fortunately, sterling silver can easily be restored to its original shine with proper cleaning and care.
How To Care For Sterling Silver Jewellery
Follow these simple tips to keep your jewellery looking beautiful:
Store Properly
Keep jewellery in:
- Soft pouches
- Jewellery boxes
- Airtight bags
Avoid Chemicals
Remove jewellery before:
- Swimming
- Cleaning
- Applying perfume
- Using beauty products
Clean Regularly
Use:
- A soft polishing cloth
- Silver cleaning cloths designed for sterling silver
Wear It Often
Interestingly, regular wear can actually help reduce tarnishing because natural skin oils help keep silver looking bright.

How To Tell If Sterling Silver Is Genuine
When purchasing silver jewellery, look for:
✓ 925 Hallmark
✓ Reputable Seller
✓ Product Description Clearly States Sterling Silver
✓ Reasonable Weight and Quality Feel
✓ Transparent Material Information
Avoid products that simply say “silver plated” if you are specifically looking for genuine sterling silver.
