The Quiet Brilliance Within, Gently Protecting You.
Wearing nature's quiet force,
close to the skin.
Why We Choose Silver 925
At SMUK, we believe in the quiet force of nature. Like the natural stones we carefully select, silver is a material that holds a gentle energy of its own — one that has accompanied human beings for millennia.
We choose Silver 925 not only for its beauty, but for its character. It is a material that harmonises with natural stone rather than competing with it. Our intention is for our jewellery to be more than ornament — to bring a sense of calm and connection to the everyday.
The light held within quietly protects you.
Silver has long been associated with the moon — a metal of intuition, emotion, and protection. Its high conductivity is said to amplify and gently regulate the energy of natural stones it is paired with. From a more grounded perspective, silver's ability to conduct and disperse energy is reflected in its physical properties.
As a material, Silver 925 contains no nickel, making it a considered choice for those with metal sensitivities. Unlike surgical stainless steel, it carries warmth and a living quality that industrial metals lack. Unlike brass, it is more resistant to discolouration and does not require nickel to achieve its alloy strength.
Every piece at SMUK is crafted with care down to what cannot be seen. The material beneath the surface is the same quality as what you wear against your skin.
Common Questions About Silver 925
Sterling Silver 925 is an alloy of 92.5% pure silver and 7.5% other metals — predominantly copper. Pure silver is too soft for jewellery use, so copper is added to improve durability without compromising the metal's character. It is the global standard for silver jewellery, combining lasting beauty with structural integrity.
Silver 925 products are generally nickel-free, which is a significant advantage for those with metal sensitivity. Nickel is the most common cause of contact dermatitis from jewellery, and its absence in Silver 925 makes it a widely trusted choice. That said, individual reactions vary, and anyone with known sensitivities should perform a patch test before extended wear.
Yes. Silver reacts with sulphur compounds in the air and with perspiration, causing the surface to gradually darken over time. Importantly, this is a surface phenomenon — the silver beneath is not degrading. A gentle wipe with a soft cloth is enough to restore the original brightness in most cases.
This natural patina is part of what makes silver alive as a material. With consistent care, it can remain beautiful for decades. For detailed guidance, see our tarnish and care guide.
"Surgical stainless steel" (SUS316L) is an industrial alloy developed primarily for cookware and medical instruments. Its entry into jewellery is a relatively recent commercial development — and its properties are fundamentally different from those of precious metals.
Importantly, 316L and similar grades of surgical stainless steel do contain trace amounts of nickel. For most people this presents no issue, but for those with heightened sensitivity, prolonged contact combined with perspiration has been associated with reactions. The claim that surgical stainless steel is "nickel-free" is not consistently accurate.
Silver 925 contains no nickel and has been used in fine jewellery for centuries. It carries intrinsic material value and a warmth that industrial metals cannot replicate. For a full comparison, see our Silver 925 vs Surgical Stainless Steel guide.
Brass is inexpensive and easy to shape, but it tarnishes more readily and may contain nickel depending on the alloy. When brass jewellery tarnishes, it can leave green marks on the skin — a result of copper oxidation. As a base metal, it holds no intrinsic precious metal value.
Silver 925 is more resistant to discolouration and is predominantly nickel-free. It is better suited to extended skin contact and retains material value over time.
A significant portion of jewellery sold as "silver" in the market consists of brass or stainless steel with a silver-coloured plating applied to the surface. They look similar, but the base material is entirely different.
Plating applied over a precious metal base — such as rhodium or gold over Silver 925 — is a legitimate process that enhances durability and surface brightness. However, when plating is applied over a non-precious base metal, wear exposes that base material directly to the skin, which can trigger allergy or cause discolouration.
The assertion that "surgical stainless steel is nickel-free" is frequently used to reassure buyers — but 316L grade stainless does contain trace nickel. The safest approach is to ask what the base material is, not just what is on the surface.
All SMUK jewellery uses Sterling Silver 925 or Gold Vermeil as the base material. Whatever the surface finish, the core of every piece remains the same quality precious metal.
