Is Sterling Silver Real Silver? Understanding Purity, Hallmarks and Craftsmanship
If you’ve ever wondered whether sterling silver is real silver, the answer is simple — yes, it absolutely is.
Sterling silver is one of the most trusted and widely used precious metals in jewellery. Made from 92.5% pure silver, it offers the perfect balance of beauty, strength and durability, which is why jewellers around the world use it to create pieces designed to be worn and loved every day.
You may sometimes notice a small “925” stamp on silver jewellery. This mark simply indicates that the piece is made from 925 sterling silver.
In the UK, jewellery that weighs over 7.78 grams must legally be hallmarked by an Assay Office to confirm its purity. However, many delicate jewellery pieces — such as fine necklaces, small pendants and earrings — naturally weigh less than this threshold and are legally exempt from hallmarking.
This means genuine sterling silver jewellery does not always carry a hallmark, particularly when designs are lightweight and detailed.
At Blackbird Jewellery, we use high-quality 925 sterling silver to create our nature-inspired designs. This metal allows us to capture the delicate textures of feathers, leaves and tiny woodland creatures while ensuring each piece remains durable enough to last for years.
Understanding how sterling silver works helps you feel confident that the jewellery you’re wearing is both genuine and made to last.
What Is Sterling Silver?
Sterling silver is a precious metal alloy made from 92.5% pure silver and 7.5% other metals, usually copper.
This blend creates a material that keeps the beauty and value of silver while adding the durability needed for jewellery.
Pure silver on its own is very soft. While it has a beautiful shine, it bends and scratches easily. By adding a small amount of copper, the silver becomes strong enough to hold its shape while still maintaining its natural brightness.
That’s why sterling silver has become the global standard for fine jewellery.
What Does “925” Mean on Silver Jewellery?
The small 925 stamp found on sterling silver jewellery is a mark of purity.
It means the piece contains:
92.5% pure silver
The remaining 7.5% is usually copper, which strengthens the metal and makes it suitable for everyday wear.
So when you see “925”, “Sterling”, or “Sterling Silver”, they all refer to the same material.
This mark is used internationally and is widely recognised as the standard for high-quality silver jewellery.
Sterling Silver vs Fine Silver vs Silver-Plated Jewellery
Not all silver jewellery is the same. Understanding the differences can help you choose pieces that will last.
Sterling Silver (.925)
Sterling silver contains 92.5% pure silver, making it strong enough for rings, necklaces and bracelets.
It is solid silver all the way through and can be polished, repaired and worn for many years.
Fine Silver (.999)
Fine silver contains 99.9% pure silver.
While it has a brighter appearance, it is much softer and more easily damaged. Because of this, it is rarely used for jewellery that needs durability.
Silver-Plated Jewellery
Silver-plated jewellery is not solid silver.
Instead, it is a thin layer of silver applied over a base metal such as brass or copper. Over time, this layer can wear away, revealing the metal underneath.
When choosing jewellery designed to last, solid sterling silver is usually the better option.
How to Tell if Silver Jewellery Is Genuine
In the UK, precious metals such as silver are protected by one of the world’s oldest systems of quality assurance: hallmarking.
If a silver item weighs more than 7.78 grams, it must legally be tested and stamped by an official Assay Office before it can be sold. These offices — such as London, Birmingham, Sheffield and Edinburgh — independently verify the metal’s purity.
A full UK hallmark usually includes:
• The fineness mark (925 for sterling silver)
• The assay office symbol (such as London’s leopard head or Birmingham’s anchor)
• The maker’s mark
Together, these marks confirm that the jewellery has been independently tested and certified.
However, many delicate pieces of jewellery — such as fine necklaces, small pendants or earrings — naturally weigh less than the 7.78 gram hallmarking threshold. Because of this, they are legally exempt from compulsory hallmarking.
In these cases you may instead see a small “925” stamp, which indicates that the piece is made from sterling silver containing 92.5% pure silver.
At Blackbird Jewellery, even our lighter pieces are crafted using genuine 925 sterling silver, chosen for its strength, beauty and longevity.
Why Jewellers Choose Sterling Silver
Sterling silver is one of the most versatile metals in jewellery making.
It allows jewellers to create detailed designs while still producing pieces that are durable enough to wear every day.
At Blackbird Jewellery we use sterling silver because it works beautifully with traditional lost-wax casting, a technique that allows us to capture the fine textures of nature.
From the delicate shape of a bird’s feather to the tiny veins of a leaf, sterling silver allows these details to be preserved in precious metal.
It also develops a natural patina over time, giving jewellery a soft glow that many people love.

A Sustainable Choice for Jewellery
Silver is also one of the most recyclable metals in the world.
It can be melted down and reused without losing its quality, which is why many jewellers — including Blackbird Jewellery — choose to work with recycled sterling silver whenever possible.
Using recycled silver helps reduce the environmental impact of mining while still creating jewellery with the same strength and beauty as newly mined metal.
For nature-inspired jewellery, it feels like the most fitting choice.
Sterling Silver Jewellery That Lasts
When you choose sterling silver jewellery, you’re choosing a material designed to be worn and treasured.
Unlike plated jewellery, solid sterling silver can be polished and cared for over time, meaning it can stay beautiful for decades.
Many pieces even become family heirlooms, passed down from one generation to the next.
That’s part of the magic of precious metals — they carry stories with them.
