Pure Silver (925 Sterling Silver)

SMUK believes in the quiet power of nature.

That is why we choose to work with materials that embody authenticity, using 925 sterling silver as our main metal.

Just like natural gemstones, silver carries a gentle energy born from the earth.

Since ancient times, it has been cherished as a symbol of intuition, emotion, and protection, quietly accompanying people through their lives.

In recent years, many accessories have been made from stainless steel or brass coated to appear silver, but even if they look similar, the difference in material makes a significant impact on how they feel against the skin and how comfortably they can be worn over time.

At SMUK, we carefully select every element with sincerity, including the parts you cannot see, to create jewelry that feels natural, comfortable, and made to be worn for years to come.

The Choice of Silver 925 — Jewelry that Lives with the Power of Nature

Silver is a beautiful metal, but it easily reacts with elements in the air, which can cause tarnishing or darkening over time.

To prevent this and to enhance its surface with an elegant platinum-like white shine, white gold plating (coating) is applied.

Pure silver has a Mohs hardness of only 2.5 to 3, meaning it’s relatively soft. By adding a surface coating, the jewelry becomes more resistant to scratches and daily wear.

At the same time, the coating helps prevent sulfur-based tarnishing, allowing the silver to maintain its bright and refined luster for longer.

⸻

At SMUK, we use K14 white gold for our white gold plating,

with a coating thickness of 2 microns.

This ensures a long-lasting, luxurious finish suitable for everyday use.

Rhodium is a rare and precious metal known for its brilliant shine and exceptional resistance to tarnish. When applied as a coating over silver, it enhances the jewelry’s brightness, protects it from discoloration and scratches, and helps maintain its beauty even with daily wear.

At SMUK, we carefully control the thickness and quality of our rhodium plating, offering a finish that meets the standards of high-end fine jewelry.

Gold Vermeil refers to a thick layer of high-purity gold plated over sterling silver (925 silver).

According to standards in the U.S. jewelry industry, vermeil must use gold of at least 10K purity and have a minimum thickness of 2.5 microns.

Features of Gold Vermeil

Gold Vermeil is made using a careful and luxurious technique of bonding melted gold onto a sterling silver base.

This process requires great skill and time, making it a premium and sophisticated material.

Thanks to the solid weight of silver and the thick layer of gold,

our vermeil jewelry offers a rich, glamorous appearance that closely resembles solid gold —

without the solid gold price tag.
