Silver 925｜Why We Choose a Material Made to Last

SMUK jewelry is primarily made from Silver 925, an alloy containing 92.5% pure silver.
Unlike stainless steel or brass with silver-colored plating, where the underlying metal may become exposed as the surface wears away, Silver 925 is made of silver throughout.

・Even if it tarnishes, its shine can be restored with polishing
・Even if the plating wears away, the underlying material remains silver
・With proper care, it can be enjoyed for many years

SMUK uses four types of plating finishes, selected according to the materials and intended use of each piece of jewelry.

• Rhodium Plating
  A finish made with a rare precious metal from the platinum group. It offers excellent resistance to tarnishing and scratches, with a clear, bright silver tone. Suitable for those with sensitive skin.
• 18K Gold Plating
  A finish made by coating sterling silver with 75% pure gold. It creates a rich, warm gold tone.
• 14K White Gold Plating
  A white gold finish with 58.3% pure gold content. Its soft, elegant white tone pairs beautifully with pearls and delicate designs.
• Gold Vermeil
  A finish featuring a thick gold layer of at least 2.5 microns over a Sterling Silver 925 base. It offers greater durability than standard plating, allowing its brilliance to last longer.
