925 Sterling Silver
At SMUK, we believe in the quiet strength of nature. That’s why we choose essential materials like 925 sterling silver—selected for more than just beauty, but for its integrity and natural energy.
Much like natural stones, silver is believed to carry a gentle energy rooted in nature, and has long symbolized intuition, emotion, and protection.
In recent years, more silver-colored products have appeared using plated brass or surgical stainless steel. While they may look similar, there are significant differences in how they feel against the skin and how they wear over time.
At SMUK, we select materials with honesty, inside and out—delivering jewelry that feels as good as it looks, and stays with you for the long run.

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).

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.
